Introducing device association for Windows Autopilot device preparation
By: Maggie Dakeva, Senior Product Manager - Microsoft Intune We’ve heard organizations want Windows deployment to be simple for employees and predictable for IT admins. But before a device enrolls, how does the organization know that the device is really one of its own - and how can IT make sure the right experience and policy reach that device regardless of who signs in? Today, we're announcing device association for Windows Autopilot device preparation, a new way to bind a physical Windows 11 device to your organization before enrollment begins. Device association uses hardware-backed attestation to create a trusted relationship between the device and your tenant at the start of the provisioning journey. That relationship helps Windows Autopilot device preparation recognize the device during the out-of-box experience (OOBE), automatically treat it as corporate-owned, and apply the experience and policy intended for that specific device. The result is a more secure, more consistent, and more device-centric onboarding flow. Start with the device, not just the user Windows Autopilot device preparation already gives IT teams a straightforward way to configure new Windows devices with the apps, scripts, and policies employees need. Device association extends that experience by allowing IT to target a device preparation policy directly to a device before it enrolls. This is especially valuable when the deployment experience needs to follow the hardware rather than the person signing in. For example, one employee can enroll multiple devices that serve different purposes, and each device can receive its own device preparation policy. When both device-based and user-based assignments are available, the device-based assignment takes precedence. That gives administrators greater confidence that the correct configuration reaches the correct device from the beginning of its lifecycle. Create a simpler out-of-box experience Because an associated device is recognized before enrollment, IT can configure more of the Windows setup experience in advance. Device association enables organizations to: Configure Language and region. Automatically configure the keyboard and skip the keyboard selection page. When the device uses a Wi-Fi network connection during OOBE, the language and keyboard selection screens aren't hidden. Hide the Microsoft Software License Terms page. Hide privacy settings during OOBE. Apply a device name template that uses the serial number or a randomized value. Hide account-change options on company sign-in and domain error pages. These controls reduce the number of decisions an employee must make while setting up a device and help create a consistent, organization-ready experience from the first screen. Strengthen trust before enrollment Device association isn't only an experience improvement. It establishes device trust earlier in the deployment process. The association uses hardware-based attestation and TPM-backed cryptographic validation to verify the device's identity. Tenant affinity is stored in the device's UEFI firmware, where it persists across a Windows reset, operating system reinstallation, or removal of enrollment. This durable, hardware-backed relationship helps ensure that the device presenting itself for preparation is the device the organization intended to onboard. Associated devices are also automatically marked as corporate-owned. If your organization blocks personally owned Windows devices with Intune enrollment restrictions, device association can be used instead of uploading a separate corporate identifier. You can continue to use corporate identifiers where they fit your process, but an associated device doesn't need both. How the device association flow works Device association is designed as a clear workflow that starts with IT and finishes automatically during OOBE: Create the device preparation policy. Configure the apps, scripts, deployment settings, OOBE experience, and optional device name template that should apply. Export the device information. During OOBE, a technician opens the Autopilot menu and exports the DeviceLink CSV with the device information required for pre-association to a USB. For an existing device, the same information can be collected from Autopilot diagnostic logs. Figure 1. The Windows Autopilot menu with Assign device association selected. ormation was exported to a removable drive. Pre-associate the device in Intune. In the Microsoft Intune admin center, go to Devices > Enrollment > Device association > Devices, upload the CSV, and optionally assign a device preparation policy directly to the device. Complete association. When the device connects to a network in OOBE, it finds the pre-association record and completes association automatically. A technician can also trigger this step manually from the Autopilot menu. Enroll and prepare the device. The device receives the applicable device-targeted policy, is marked as corporate-owned, and presents the configured OOBE experience. Monitor the deployment. Administrators can review association state and assigned policy in the Device association blade and filter devices by state, policy, manufacturer, or model. The device association lifecycle consists of the following states: Pre-associated: The device was added on the service side and is waiting to complete association in OOBE. Associated: The device completed association by writing the tenant affinity to UEFI and is ready for enrollment. This happens automatically when a pre-associated device syncs with an MDM provider. Pending removal: A request to remove the pre-association is being processed. A device's association can be removed by an administrator or partner with physical access to the device who manually runs a local script that clears the tenant affinity information stored in the device's UEFI. This action should be performed only when the device should no longer be associated with the organization, such as when it is sold, recycled, or transferred. Manage the full device lifecycle The association remains with the device through reset and reinstallation, helping preserve the organization's intended provisioning path when a device is redeployed internally. When a device permanently leaves the organization - for example, when it's sold, recycled, or transferred—the association should be removed as part of decommissioning. Because the tenant affinity is stored on the device, clearing a completed association can be performed via script locally on the physical device, without access to the service. This lifecycle model is intentional: association is durable during normal reuse inside the organization, while permanent removal can be completed by an admin or partner who has control of the physical device. Designed to work alongside your existing Windows Autopilot strategy Device association is part of Windows Autopilot device preparation and can coexist with traditional Windows Autopilot deployments in the same organization. For a device already registered with Windows Autopilot, the association state determines which deployment runs. If the device isn't associated, its Windows Autopilot registration takes precedence. If it is associated, the Windows Autopilot device preparation deployment takes precedence. This gives organizations a practical path to introduce device association while continuing to support existing Windows Autopilot investments. Get started To use device association, you'll need a supported physical Windows 11 device with TPM 2.0 enabled and in a healthy state. Virtual machines aren't supported because device association relies on hardware-backed identity verification. Start by reviewing the Windows Autopilot device association requirements, then create or update your Windows Autopilot device preparation policy. From there, export the device information, pre-associate the device in Intune, and let Windows complete the trusted association during OOBE. With device association, Windows Autopilot device preparation moves device trust, targeting, and customization earlier in the deployment journey - before enrollment and before the employee reaches the desktop. That means fewer setup decisions for users, more predictable deployments for IT, and stronger confidence that the right device is joining the right organization with the right configuration.

By: Maggie Dakeva, Senior Product Manager - Microsoft Intune Organizations have spent years refining Windows Autopilot deployments. Profiles, Enrollment Status Page settings, group tags, dynamic groups, application assignments, and support processes all work together to deliver a familiar provisioning experience. Windows Autopilot device preparation is a re-architecture of Windows Autopilot designed around the customer asks we hear most often: simpler configuration, faster and more reliable setup, clearer progress for users, and near real-time deployment reporting for administrators. A single device preparation policy brings deployment and the out-of-box experience (OOBE) settings together, enrollment time grouping (ETG) places devices into the right security group during enrollment, and granular application and PowerShell script status makes troubleshooting easier. Autopilot device preparation is now the recommended solution for user-driven scenarios. Future engineering investments will focus on Windows Autopilot device preparation, enabling organizations to benefit from ongoing improvements to provisioning, reliability, reporting, and support. Moving eligible deployments positions your organization to benefit from those ongoing improvements while reducing the complexity of provisioning and support. So how do you move without disrupting devices that are already working - or forcing every deployment scenario to transition at once? The answer is a phased approach. Windows Autopilot and Windows Autopilot device preparation can coexist in the same organization. You can move eligible user-driven Microsoft Entra join populations in controlled waves, validate the full experience, and keep scenarios that still require Windows Autopilot on their existing path. The result is a practical way to adopt a simpler provisioning model while protecting the investments and workflows your organization still depends on. Start with the outcome, not a one-for-one migration Windows Autopilot device preparation brings enrollment settings, OOBE, device naming, required applications, PowerShell scripts, and enrollment-time targeting into a more coherent policy flow. The device preparation page, which replaces the Enrollment status page, gives users clearer progress and gives administrators more detailed deployment status for troubleshooting. Windows Autopilot device preparation includes two complementary capabilities: Device preparation policy defines the deployment experience, including OOBE settings, applications, scripts, naming, and ETG. Device association optionally binds a physical device to your organization before enrollment. It can establish corporate ownership and tenant affinity, enable associated-device OOBE settings, and support direct per-device policy assignment. Based on organizational needs, customers can choose to use device preparation policy, device association, or both. Device preparation policy provides the deployment configuration and experience, while device association adds pre-enrollment device affinity and device-based capabilities. Organizations can adopt each capability where it adds value to their provisioning model. But moving to that model shouldn't mean recreating every Windows Autopilot object exactly as it exists today. Instead, begin with the outcome each device population needs. Identify the required OOBE behavior, applications, scripts, naming, assignments, and support experience. Then design the device preparation policy and ETG model that delivers that outcome. This approach reduces inherited complexity and helps ensure that the new deployment is designed for Windows Autopilot device preparation and not constrained by the architecture it replaces. Choose what moves - and what stays Windows Autopilot device preparation is the recommended path for eligible user-driven provisioning scenarios, including: Corporate-owned Windows 11 devices User-driven Microsoft Entra join Windows 365 Continue using Windows Autopilot for scenarios that aren't supported or recommended for transition, including: Pre-provisioning Self-deploying mode Hybrid Microsoft Entra join Autopilot into co-management This isn't an all-or-nothing decision. The right transition plan deliberately separates eligible populations from valid exceptions. Translate the provisioning model Several familiar Windows Autopilot concepts have a corresponding role in Windows Autopilot device preparation: Windows Autopilot Concept Windows Autopilot Device Preparation Model Deployment profile Device preparation policy Enrollment Status Page profile Device preparation policy Enrollment Status Page in OOBE Device preparation page in OOBE Windows Autopilot registration Optional device association Profile and dynamic group-based targeting based on group tags Granular device preparation policy assignment with enrollment time grouping (ETG) using Microsoft Entra static security groups Device name template defined in the Autopilot deployment profile Device name template defined in the device preparation policy Windows Autopilot deployments report Windows Autopilot device preparation deployments report The goal is to preserve the required customer and administrator experience - not every historical configuration object. How the transition flow works A controlled transition can follow eight steps: Define the eligible population: Start with corporate-owned Windows 11 devices using user-driven Microsoft Entra join. Exclude scenarios that should remain on Windows Autopilot. Design enrollment time grouping (ETG): Create assigned, static Microsoft Entra security groups for populations that genuinely differ by location, role, device type, or required configuration. Don't build the new design around a group tag or a device object that must exist before enrollment. Create device preparation policy equivalents: Inventory each deployment profile and Enrollment Status Page pairing. Map the required OOBE settings, naming, applications, PowerShell scripts, blocking requirements, and dependencies into the new device preparation policy. Evaluate whether device association is required for all scenarios. For user-targeted deployments that don't need pre-enrollment tenant affinity or per-device policy selection, the organization can use the device preparation policy without device association and simplify the setup and management of device onboarding. For devices that need automatic corporate ownership, OOBE customization settings, or stronger pre-enrollment trust, continue with step 5. Pre-associate eligible devices. For existing registered or enrolled devices, collect the pre-association information by collecting the diagnostics logs, then exporting the DeviceLink CSV file found in the logs. Upload the CSV in the Associated devices blade in Intune and assign a device preparation policy to the device. Assignment can be done during the CSV upload process or after. Confirm that the device reaches the Pre-associated state before its planned reset or refresh. Note: Device pre-association is only available for devices that meet the minimum OS and hardware requirements , including TPM 2.0. Pilot the complete OOBE experience. Start with new devices or reset a small, representative set of devices. Validate policy selection, ETG placement, applications, scripts, naming, progress reporting. Expand and pre-associate remaining devices. Pre-associate additional populations in controlled waves. You do not need to force resets to all existing enrolled devices but simply pre-associate to prepare them so they enroll via the Windows Autopilot device preparation flow whenever each device next undergoes a natural or required reset. Retire registered flows. Retire deployment profiles, Enrollment Status Page profiles, groups, registrations, and processes only after reporting confirms that no active or planned population still depends on them. Pre-association doesn’t reset the device or disrupt its current use. The device remains enrolled and productive until its next natural or required reset, when Windows Autopilot device preparation takes effect. Don't remove the Windows Autopilot registration early. Doing so can remove Autopilot properties and affect dynamic-group membership that supports the device's current configuration. The next time the device enters OOBE, Windows recognizes the association and follows the Windows Autopilot device preparation path. If a device is both registered and associated, association takes precedence. Plan the pilot around this behavior rather than expecting an automatic fallback to Windows Autopilot. OEM and partner note: Device association uploads are currently only supported through Intune. OEM and partner pre-association scenarios aren't supported yet, but they’re on the roadmap. What this means for your organization You can prepare existing devices for transition while they remain enrolled and in use. You can move one eligible population at a time instead of committing to an organization-wide cutover. You can preserve Windows Autopilot for scenarios that still require it. You can use the transition to simplify assignment and provisioning logic rather than carry every legacy object forward. You can retire the old configuration gradually - after validation and dependency checks confirm that nothing still relies on it. A sample customer pilot setup scenario Consider a multinational organization, Contoso, that uses group tags to distinguish devices in the United Kingdom and Germany and to identify different device use cases. Dynamic groups use those tags to determine which deployment profile, Enrollment Status Page configuration, applications, policies, scope tags, and naming rules apply. The organization wants to move its eligible user-driven Windows 11 populations to Windows Autopilot device preparation without reproducing the same pre-created record and dynamic-group dependencies. The Contoso deployment team transitions to Autopilot device preparation with the following steps: Create static security groups for each required configuration. The team creates assigned Microsoft Entra security groups such as User Devices UK and User Devices Germany. It creates separate groups only when location, role, device type, scope, or required configuration differs. Create a device preparation policy for each population. The team creates a policy such as User Devices UK DPP and User Devices Germany DPP. Each policy contains the required OOBE settings, applications, PowerShell scripts, blocking behavior, and device name template, and identifies the corresponding enrollment time grouping (ETG) security group. Assign the device preparation policies to each population. The team assigns each device preparation policy to the respective sets of devices at time of pre-association or later. During enrollment, the device joins the group selected by the device preparation policy. For example, devices assigned the User Devices UK DPP join the User Devices UK group and receive the apps and policies assigned to that group. Configure scope through the static groups. The team assigns the appropriate regional scope tag to each ETG security group. The device receives the associated scope tag when it joins the group during enrollment. Set a naming template for each device preparation policy. The organization uses a naming convention where devices start with a prefix indicating their location. The team sets UK-%SERIAL% in User Devices UK DPP and DE-%SERIAL% in User Devices Germany DPP. Pre-associate pilot devices without disruption. Selected devices can be pre-associated while they remain enrolled and in use. The team collects diagnostics logs via script, extracts the DeviceLink CSV files, imports them in Intune, confirms the devices reach the Pre-associated state, and keeps the Windows Autopilot registration in place until the approved reset or refresh window. Validate the end-to-end experience with representative devices. The admin team uses test devices representing each target population to verify policy assignment, static group membership, scope tags, naming, applications, scripts, reporting, and successful completion of the device preparation flow. Existing devices can remain in service until their next natural or required reset. Seven-step regional Windows Autopilot device preparation rollout workflow, from creating security groups and device preparation policies through regional configuration, pilot association, and device validation. This scenario is illustrative, not a completed deployment or a measured customer outcome. It shows the transition pattern: define the supported scope, replace group-tag dependencies with ETG, move Enrollment Status Page and deployment profile settings to the device preparation policy, decide where device association adds value, validate end to end, and expand in controlled waves. Get started Begin with one eligible user-driven Microsoft Entra join population. Map its current Windows Autopilot outcomes to enrollment time grouping (ETG) and a device preparation policy. Pre-associate a representative pilot, validate the complete reset-to-desktop experience, and expand only when the results meet your deployment and support criteria. Moving to Windows Autopilot device preparation doesn't require a forced cutover. It requires a clear boundary, a deliberately redesigned assignment model, and evidence from each wave. That gives IT a controlled path toward simpler provisioning while keeping every device population on the experience that supports it best.

Today, some organizations use an EnterpriseEnrollment DNS CNAME record to automatically direct devices to the Microsoft enrollment service during Windows MDM-only enrollment. Starting January 15, 2027, as part of our ongoing efforts to simplify and modernize enrollment experiences, Microsoft Intune will end support for CNAME-based auto-discovery in Windows MDM-only enrollment scenarios. This change reduces dependency on DNS-based discovery while providing a more consistent enrollment experience moving forward. After this change, users may need to enter the Microsoft enrollment server URL if it’s not already provided by the enrollment experience: https://enrollment.manage.microsoft.com/enrollmentserver/discovery.svc Who this change affects Your organization may be affected if: You use Windows MDM-only enrollment. You have configured an EnterpriseEnrollment DNS CNAME record. Your enrollment process depends on DNS record to automatically discover the enrollment service. You likely aren't affected if you exclusively use: Microsoft Entra join enrollment Microsoft Entra hybrid join enrollment Other enrollment methods that don't rely on EnterpriseEnrollment CNAME discovery How the user experience will change Today, in affected environments, a user can begin Windows MDM-only enrollment, and the enrollment service is automatically discovered using the organization’s EnterpriseEnrollment DNS CNAME record. The user doesn’t need to provide the enrollment server information. After this change, CNAME-based auto-discovery will no longer be used for these Windows MDM-only enrollment scenarios. If the enrollment service URL isn't already provided by the enrollment experience, the user will need to enter it when prompted. Enrollment can then continue using the Microsoft enrollment service URL. For example: Identifying affected environments Review your organization's DNS configuration and Windows MDM-only enrollment documentation.In particular, look for an EnterpriseEnrollment DNS record similar to: EnterpriseEnrollment.contoso.com If your organization configured the EnterpriseEnrollment record to support Windows MDM-only enrollment discovery, you should prepare for this change. You should also review and update documentation that assumes enrollment service discovery happens automatically through DNS, including: Internal enrollment guides Help desk procedures Device deployment instructions Provisioning documentation User onboarding materials Actions to take if you’re affected To prepare for this change we recommend the following actions: 1. Identify impacted enrollment workflows Review all Windows MDM-only enrollment scenarios used within your organization and determine whether they depend on EnterpriseEnrollment DNS discovery. 2. Update enrollment documentation Update user guides, knowledge base articles, onboarding materials, and other instructions to reflect the new enrollment process. 3. Prepare support teams Ensure help desk and deployment teams understand the change and know when the enrollment service URL may need to be provided. 4. Test enrollment scenarios Validate affected enrollment workflows before the change takes effect. Identify any required updates and determine where users may be prompted to enter the enrollment service URL. 5. Communicate with impacted users If users will need to enter the enrollment service URL, provide updated instructions before the change takes effect. Frequently asked questions Does this affect existing enrolled devices? No. Existing enrolled devices remain enrolled and aren’t affected by this change. Is Windows MDM-only enrollment being retired? No. Windows MDM-only enrollment remains supported. Only CNAME-based auto-discovery will become unsupported. Do I need to remove my EnterpriseEnrollment DNS record? Review your environment and DNS configuration requirements. This change only affects use of the record for Windows MDM-only enrollment auto-discovery. Will every user need to enter the enrollment service URL? Not necessarily. Some enrollment experiences may already provide enrollment server information. Manual entry is only required when the enrollment experience doesn’t provide it automatically. Should we begin testing now? Yes. We strongly recommend validating enrollment scenarios as early as possible and updating relevant documentation before this change takes effect. Next steps Review your Windows MDM-only enrollment processes and identify any dependencies on EnterpriseEnrollment DNS CNAME records. Update enrollment guidance, deployment instructions, onboarding materials, and help desk procedures that assume the enrollment service will be discovered automatically through DNS.

By: Per Larsen - Senior Product Manager | Microsoft Intune For many organizations, Group Policy Objects (GPOs) remain an important part of Windows configuration. As device strategies expand to include cloud-native management, Microsoft Intune provides the policy platform for devices that are Microsoft Entra joined and managed from the cloud. The goal isn’t to force every organization through the same migration, it’s to choose the right management path for each device population and each setting. This guide explains three common paths: starting fresh for new cloud-native devices, selectively transitioning required settings to Intune, and coordinating GPO with Intune for hybrid Microsoft Entra joined or co-managed devices. Across all three paths, the recommended principle is the same: assess and rationalize existing policy before deciding what to retain, re-create, redesign, or retire. 1. Choose the right path for each device population GPO was designed primarily for domain-joined, on-premises devices. Intune, in contrast, is designed for cloud-based management of devices whether they are on or off prem. The right path will depend on the scenario in which the devices are joined and managed. Scenario 1: Start fresh for new cloud-native devices This is the recommended approach for new Microsoft Entra joined devices. Invest in the cloud-first configuration you need today rather than reproducing every historical GPO. Begin with mandatory security requirements, Microsoft-recommended security baselines, and essential settings for services such as OneDrive and Microsoft Edge. Add other settings only when there’s business, security, or operational requirement. Scenario 2: Selectively transition required settings Organizations that need to preserve specific behavior can assess and rationalize existing GPOs, then re-create only the settings that are supported and necessary in Intune. Treat this as a deliberate replatforming effort, not a one-to-one copy. Test each new profile with a pilot group before broad deployment. Scenario 3: Coordinate GPO and Intune for hybrid devices Hybrid Microsoft Entra joined devices may receive settings from both GPO and Intune, including common scenarios where Intune-managed workloads or Windows Autopatch are used for existing hybrid domain-joined devices. Use of both group policy and Intune policy enforcement can continue for an extended period, but you should plan carefully to avoid conflicting settings. Organizations can either leave existing GPOs in place until devices are rebuilt as cloud-native, or actively shift selected policy areas to Intune while the devices remain hybrid joined. Figure 1. A cloud-first policy workflow begins with assessment and rationalization, then applies the appropriate path for each device population. 2. Assess and rationalize before you transition Before changing policy source, understand what’s actually in use. Many environments contain GPOs that are old, undocumented, duplicated, or applied more broadly than intended. A direct lift-and-shift carries that technical debt into Intune. Key assessment actions Export all GPOs from Group Policy Management Console (GPMC). Use Gpresult and operational knowledge to identify which GPOs are still applied and functional. Remove or archive unused, legacy, or duplicated policies instead of transitioning them. Categorize required settings by security, update management, device restrictions, application control, and legacy or unsupported scenarios. Record the device populations and business requirements associated with each policy. 3. Use Group Policy Analytics as an assessment input Microsoft Intune includes Group Policy Analytics, a built-in tool that imports on-premises GPOs and reports their mapped support in mobile device management. It can help identify settings with Intune equivalents, deprecated settings, and configurations that may require another implementation approach. Use the report as one source of evidence rather than as a complete transition engine. Its mappings may not reflect every setting currently available in the Settings Catalog, especially settings added after the analytics mapping was last updated. Validate important settings directly in Intune and against current Microsoft documentation. Useful outcomes Highlights settings with documented Intune mappings. Surfaces GPO settings that no longer make sense for cloud-native devices. Helps identify GPOs that should be retired rather than re-created. Supports, but does not replace, business validation and pilot testing. 4. Don't lift and shift: Re-design for cloud-first management A direct copy of GPOs into Intune can reproduce policy sprawl and create new conflicts. Instead, use the assessment to determine the intended outcome of each setting. Some settings will be unnecessary, some will have a direct Intune settings catalog equivalent, and others will need a cloud-appropriate redesign. Retire settings that are no longer required. Re-create settings that are supported and necessary. Rethink and redesign legacy dependencies such as drive mappings, printers, or vendor-specific prioritizing or considering cloud-first solutions and configurations. Document the owner, target population, and validation method for each resulting Intune profile. Figure 2. Decide whether to retain, re-create, redesign, or retire each GPO based on device type and current business need. 5. Start with security baselines Security baselines in Intune are curated collections of Microsoft-recommended settings for Windows, Microsoft Edge, and Microsoft Defender. They provide a controlled foundation that can reduce policy sprawl and align devices with current security guidance. Review baseline settings with security stakeholders rather than applying them without evaluation. Identify overlaps with existing policies before deployment. Pilot the baseline with representative devices and users. Layer additional configuration policies only for documented requirements. 6. Create equivalent Intune configuration profiles where needed After assessment and baseline planning: Configure supported and necessary settings in the settings catalog. Use Administrative Templates or imported ADMX policies for applicable settings. Use custom configuration, scripts, or remediations only when a built-in option doesn’t meet the requirement. Use standard or organizational safe rollout practices to assign policies before broad rollout, and monitor deployment and conflict reports. 7. Coordinate GPO and Intune during a hybrid period Customers often expect GPOWinsOverMDM to act as a universal precedence switch: whenever Group Policy and Intune configure the same setting, GPO should win. In reality, conflict control applies only to the subset of settings exposed through the Windows Policy CSP with corresponding Group Policy mappings. Additionally, it doesn’t govern settings delivered through other CSPs, such as Defender or Windows Update. Those policy areas can have different precedence, merging, or conflict behavior. Consequently, using GPOWinsOverMDM as a coexistence strategy can produce inconsistent and difficult-to-predict results. The safer approach is to avoid configuring the same setting through both management planes. Use targeted groups, assignment filters, GPO security filtering, and Organizational Units (OU) scoping to establish one authoritative source for each setting and device population. Use selective targeting to move policy areas in controlled stages: In Group Policy, use appropriate OU link placement, security group filtering, and carefully validated Windows Management Instrumentation (WMI) filters to stop selected GPOs from applying to devices that will receive the Intune equivalent. In Intune, use Microsoft Entra groups, dynamic membership rules, assignment filters, and exclusions to target the intended device population. For each policy area, document the authoritative management plane and the date or condition for changing ownership. Validate effective configuration with Gpresult, Intune reports, Event Viewer, and representative pilot devices. For example, an organization might leave most existing GPOs in place for hybrid joined devices while excluding a pilot group from the Windows Update GPO. The same group can then receive the corresponding Intune update policy. After validation, you can expand the targeting changes in stages in alignment with your organizational safe-rollout standards. 8. Common Pitfalls Enforcing GPO and Intune side by side without coordinated targeting Uncoordinated configuration can create conflicts, inconsistent results, and difficult troubleshooting. Define an authoritative management plane for each setting and device population. Transitioning everything as is You should rationalize old, unused, or duplicated settings rather than reproducing or recreating them in Intune. Supporting legacy or non-cloud-first settings. Some requirements don’t have a direct built-in Intune equivalent. Evaluate whether the requirement is still necessary, then use a supported alternative, redesign the process, or retain the setting in GPO for the applicable hybrid devices. Skipping the pilot phase Pilot groups reveal assignment, compatibility, and user-impact issues before a broad deployment. 10. Retire old GPOs gradually Retire a GPO only after its replacement or removal has been validated for the affected device population. Exclude a pilot population from the original GPO and assign the intended Intune configuration. Validate effective settings, Intune deployment status, device events, and user impact. Expand the targeting change in controlled stages. Disable and archive the GPO after dependencies are removed and rollback is no longer required. Keep GPOs that remain necessary for hybrid joined devices, with clear ownership and targeting. Conclusion Moving to Intune policy management isn’t a one-size-fits-all migration or a copy-and-paste exercise. For new cloud-native devices, start with a clean, cloud-first configuration. When existing behavior must be preserved, assess and rationalize the requirement before re-creating it in Intune. During a period of parallel Group Policy and Intune management, coordinate targeting so GPO and Intune do not compete for the same settings. The key principles are: Choose the management path by device population. Assess and rationalize before making changes. Start with security requirements and validated baselines. Use Group Policy Analytics as an input, not as the sole source of truth. Transition only supported and necessary settings. Coordinate GPO and Intune targeting throughout any transition period.Registry Inventory in Microsoft Intune: Verifying What’s on Your Devices
By: Madison Cooks, Product Manager | Microsoft Intune IT admins need a reliable way to confirm how Windows devices are configured, especially when troubleshooting, validating compliance, or investigating security posture. Policy assignment alone doesn’t always show what’s present on the device and getting registry visibility at scale has often required custom discovery or remediation scripts that take time to build, test, and maintain. With Microsoft Intune’s July (2607) release, device inventory will include Windows registry data, helping IT admins verify a device’s actual configuration, not just the policy assigned. With a new Device inventory property for registry keys, you define the keys you care about in the properties catalog, and Intune collects them for you. There’s no collection logic to build or keep running. This makes registry-based configuration checks easier to operationalize across managed Windows devices, so teams can spend less time maintaining scripts and more time acting on the data. Figure 1: Microsoft Intune device inventory profile creation screen showing the Properties picker with the Registry category selected for inventory data collection. What registry data you collect Registry data collection is configured through the existing properties catalog. For each entry, provide a registry key path and, when needed, a value name. For every targeted device, the device agent attempts collection and reports: Registry key path Value name Value type Value data Microsoft Intune device inventory profile configuration page showing registry key collection settings, including registry path, collection pattern options, and value name fields. The initial release supports the following collection patterns designed for common admin scenarios that use HKEY_LOCAL_MACHINE (HKLM) paths. Single value Specify a registry path and value name to collect one value from that path. For example, collect Secure Boot certificate servicing status from HKLM\SYSTEM\CurrentControlSet\Control\SecureBoot by using values such as UEFICA2023Status, UEFICA2023Error, or UEFICA2023ErrorEvent. All values under a path, non-recursive Specify a registry path to collect all values directly under that path. This pattern doesn't include subkeys. For example, collect values directly under a Windows Update configuration path to help validate expected settings. Same value across subkeys Specify a base registry key path and a value name to collect that value from each immediate subkey. For example, collect DHCP status across network interface subkeys under HKLM\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\Interfaces. Where registry inventory data appears After collection, registry inventory data will be available in Device inventory at initial release. We’ll expand access to registry data in the coming months, including support in additional reporting and exploration experiences. Microsoft Intune Device Inventory page displaying collected Windows registry data for a device, including registry key paths, values, collection status, and timestamps. This makes registry data available alongside other inventory signals, so admins can use familiar tools to investigate configuration, validate device state, and support troubleshooting without building separate collection scripts. How admins use this You can collect registry data and view it per device in Device inventory - a verified record of each endpoint’s actual configuration and a key source of settings data on each endpoint. This helps answer questions like: Is a setting actually enabled on the device? Which app, version, or configuration is installed? Did a policy apply correctly? Why is this device behaving differently from the rest? Registry data collection in Device inventory is included with Microsoft Intune Plan 1. Collection results and limits If a registry value exists but doesn’t contain data, collection succeeds and the value appears as empty. If the registry path or value name doesn’t exist on a device, that device reports Not found for the collection result. Collection continues for all other devices, so one missing value won’t block results from devices where the value exists. Registry inventory includes safeguards to keep collection focused and manageable. Each collected registry value is capped at 6 KB, and each device can collect up to 100 registry keys. If a value or device exceeds these limits, collection skips the excess data and reports the applicable result for that device. These limits help manage data volume, maintain service performance, and reduce the risk of over-collection. Registry inventory is designed for configuration visibility and troubleshooting, not for collecting sensitive or confidential data. Built-in heuristic detection helps identify and prevent ingestion of values that may contain secrets, credentials, authentication tokens, certificates, private keys, connection strings, or other data that could grant access if exposed. If a value is flagged as potentially sensitive, it isn’t collected. Collection is limited to HKEY_LOCAL_MACHINE (HKLM) paths. This keeps inventory focused on device-level configuration and avoids user-specific registry contexts. Summary Registry inventory in Microsoft Intune helps admins collect Windows registry data in a native, declarative way. Instead of maintaining custom scripts for common inventory scenarios, admins can configure registry collection in the properties catalog and query the results through familiar Intune reporting experiences. Use registry inventory for configuration visibility and troubleshooting across managed Windows devices. As you plan your collection strategy, focus on device-level HKLM data, avoid sensitive values, and remember collection limits to keep inventory targeted and manageable.

Rethinking “Allow my organization to manage my device” Why opt‑in enrollment works better for Intune
By: Ramya B Sharma – Senior Software Engineer | Microsoft Intune A new public preview feature in Microsoft Intune, we’ve introduced a toggle that allows admins to block automatic mobile device management (MDM) enrollment during the modern app sign-in flow on Windows. This enhancement directly responds to frequent customer requests for greater control over device enrollment, specifically the ability to prevent automatic MDM enrollment on Windows devices during app sign-in. While Microsoft Entra generally recommends automatic enrollment by default, most Intune customers - especially those supporting bring your own device (BYOD), mixed ownership, or multi-tenant access scenarios - benefit from an opt-in enrollment model instead. Recommended best practice Keep “MDM user scope” set to All so enrollment is available when needed, but configure the new toggle “Disable MDM enrollment when adding a work or school account on Windows” to Yes so MDM enrollment is not automatically selected by default during app sign in. This ensures devices are enrolled into Intune only through intentional enrollment flows, reducing accidental enrollments, support burden, and difficult recovery scenarios. Learn more: Automatic MDM enrollment in the Intune admin center. Why this matters For years, Windows users signing into work or school apps have been presented with: “Allow my organization to manage my device.” In most environments, this option was selected by default or clicked through without full understanding. That single action could result in: Microsoft Entra device registration Automatic Intune MDM enrollment Immediate policy application to the device For IT teams, this often led to: Unintended device enrollments Personal or BYOD devices becoming fully managed Difficult unenrollment and recovery experiences The new public preview toggle directly addresses these long‑standing issues. How the modern app sign in enrollment flow works When a user signs into a Microsoft work or school app on Windows, Windows may start a device registration flow. Historically, if: Automatic enrollment was enabled, and The user was in the MDM user scope Then registration could immediately turn into full MDM enrollment, even though the user only intended to sign into an app. What the new toggle changes The new setting“Disable MDM enrollment when adding a work or school account on Windows”: Allows account registration Stops the flow before MDM enrollment Removes the “Allow my organization to manage my device” screen from the app sign-in flow Preserves intentional enrollment paths Important: This setting applies to modern app sign in flows, not Windows settings–based enrollment. Allowing enrollment versus forcing enrollment This distinction is critical. Allowing enrollment: MDM user scope is configured to “All” or “Some” Enrollment is available when needed Devices enroll through deliberate flows Forcing enrollment Enrollment triggered implicitly App sign in becomes an enrollment decision Users may not realize the device is managed Recovery is harder later The new toggle lets organizations separate these behaviors. Impact across common Windows enrollment scenarios Scenario Default behavior Opt-in recommended behavior BYOD / personal devices High risk of accidental enrollment App access without device takeover Microsoft Office / Teams sign in May initiate MDM enrollment No MDM enrollment unless user chooses Microsoft Entra hybrid join (corporate) Microsoft Entra joined Microsoft Entra joined Windows settings enrollment MDM enrollment MDM enrollment Windows Autopilot / provisioning MDM enrollment MDM enrollment Security and governance benefits Opt-in enrollment supports: Least surprise Explicit consent Cleaner BYOD posture Safer break glass scenarios Reduced support escalations It also aligns well with Conditional Access and app level protection strategies. When to use the default behavior Default automatic enrollment may still be appropriate for: Fully corporate owned device fleets Locked down environments Dedicated provisioning scenarios The key is that it should be a conscious decision, not an accidental one. Summary In conclusion, for most organizations, the modern best practice is: Allow enrollment everywhere - require intent. Using the new Intune toggle to make enrollment opt-in during app sign in reduces risk, improves user trust, and simplifies the device lifecycle - without sacrificing Intune’s management capabilities. Recommended reading: For a concrete example of the end‑user experience with this model, see Step 6: Understand Microsoft Edge for Business End User Experience for Windows, which walks through how opt‑in enrollment and app‑level management are presented to users in Microsoft Edge for Business.

By: Carlos Diaz - Sr. Product Manager and Jason Sandys - Principal Product Manager | Microsoft Intune Delivery Optimization is built into Windows and can help reduce bandwidth usage during app and update deployments. Instead of downloading content from the internet every time, devices can download it from nearby devices or a local cache when available. Many organizations leave Delivery Optimization at its default settings or disable it entirely. As a result, they may miss opportunities to reduce network traffic, improve deployment performance, and make better use of existing network resources. This article focuses on the Delivery Optimization scenarios and the common configurations that Intune admins use most often: large-scale patching, Windows Autopilot provisioning, branch office bandwidth management, and Microsoft Connected Cache for scenarios where peer-to-peer sharing alone isn't enough. How Delivery Optimization works Delivery Optimization is an HTTP downloader with built-in peer-to-peer capabilities available in supported versions of Windows. It helps distribute Windows updates, Microsoft 365 Apps updates, Microsoft Defender definition updates, Microsoft Store apps, Intune Win32 apps package and other supported content. Delivery Optimization checks local sources before falling back to internet content caches. The most important Delivery Optimization policy setting is Download Mode, which determines how devices discover peers. Mode Description Mode 1 (LAN) Devices share content with peers behind the same IP/NAT boundary. Mode 2 (Group) Devices share content within a defined group, such as an Active Directory site, domain, or custom group ID. Recommended for environments with multiple VLANs or segmented networks. Mode 3 (Internet) Devices can share content with internet peers outside the organization. This mode is rarely used in enterprise environments. Delivery Optimization checks sources in this order: LAN or group peers and, if configured, Microsoft Connected Cache in parallel. Internet peers, if allowed in the Download Mode setting Internet content caches, which are always available as the final fallback Regardless of the mode you choose, the goal is to keep content download traffic local whenever possible. Common misconceptions Before configuring Delivery Optimization, it's worth addressing a few common misunderstandings we’ve heard from customers. "Does Delivery Optimization use my bandwidth to upload content to the internet?" In Mode 1 (LAN), peer sharing is restricted to your local subnet. Content is only shared with other devices on the same network segment, and no content leaves your LAN. Additionally, you have full control over upload usage through the Monthly upload data cap setting. "Is Delivery Optimization the same as BranchCache?" While both technologies help reduce bandwidth usage, they are built on different architectures and support different scenarios. BranchCache relies on BranchCache-enabled content servers to cache and distribute content, whereas Delivery Optimization is built directly into Windows and is designed to work natively with cloud-delivered content, including Windows updates, Microsoft Store apps, and Microsoft 365 Apps. "We disabled Delivery Optimization years ago. Is there any reason to revisit it?" Yes. Delivery Optimization has evolved significantly and now offers extensive management capabilities through the Intune Settings Catalog. Administrators can configure download modes, define group boundaries, control bandwidth usage, set cache sizes, and limit uploads. If Delivery Optimization was disabled in the past, it may be worth reevaluating your configuration. When properly configured, it can help reduce bandwidth consumption, improve content distribution efficiency, and accelerate update and application deployments. Essential policies The following settings, available in the settings catalog under Delivery Optimization, provide you a strong starting point: Setting Default Value* Recommended Value What It Does DODownloadMode 1 (LAN) 1 (LAN) Keeps peer-to-peer sharing within your subnet or Delivery Optimization group. DORestrictPeerSelectionBy 1 1 Devices discover and peer with others on the same subnet. DOMaxCacheSize 20% 20% to 30% Amount of local disk space allocated to the Delivery Optimization cache. DOMinFileSizeToCache 50 MB 5 MB Minimum file size eligible for caching and peer-to-peer distribution. DOMaxCacheAge 259,200 seconds (3 days) 1,209,600 seconds (14 days) Determines how long cached content remains available before cleanup. DOMonthlyUploadDataCap 20 GB 20 GB Limits the total amount of data a device can upload to peers each month. *The default values in this table are for Windows 11. The table above lists common Delivery Optimization settings, their default values, and recommended starting values. However, the best configuration depends on your network topology, device count, update cadence, and whether you’re using Microsoft Connected Cache. Use the scenario guidance below to tune from the baseline. for the full policy reference review: Configure Delivery Optimization (DO) for Windows. The defaults provide some immediate value, but organizations often achieve better results by: Defining peer groups Increasing cache size Increasing retention periods Lowering the minimum file-size threshold when appropriate When configuring Delivery Optimization, avoid managing the same setting from multiple locations, such as settings catalog and custom policy. Using the settings catalog as your primary management location can help reduce conflicts and simplify troubleshooting. Windows quality updates, feature updates, and Office updates are typically the largest bandwidth consuming events most organizations face. A 1 GB cumulative update pushed to 10,000 devices means 10 TB of traffic from the internet unless Delivery Optimization lets devices share locally. This is where properly configured Delivery Optimization pays for itself immediately. Coordinate Delivery Optimization with deployment rings. Start with a small seeder ring, typically 5 to 10 percent of devices, so those devices populate peer caches before broader rings begin hours or days later. If Microsoft Connected Cache is deployed, the same seeder ring also populates the cache node, creating a persistent local source for later rings. Scenario 1. Large-scale update deployments Large scale deployments vary greatly in complexity and challenges. Device count isn’t the only factor to consider. Network infrastructure and configuration can also play a role in your configuration and deployment of Delivery Optimization. How you tune Delivery Optimization for large-scale updates depends heavily on your WAN topology. The two most common designs call for different approaches: Star (hub-and-spoke) topology Branches connect to a central hub; internet traffic may be backhauled. Every update byte a branch device pulls from the internet crosses the internal link between the hub and spoke. Group boundaries: Identify local LAN configurations at branch locations. If all devices at a branch location are on a single subnet, use DODownloadMode = 1 with DORestrictPeerSelectionBy=1 to restrict peers to that subnet. If a branch site has multiple subnets, DODownloadMode = 2 with a branch-specific DOGroupID is more effective because devices can discover peers throughout the branch instead of being limited to their local subnet. Tip: Delivery Optimization Has Evolved Many organizations disabled Delivery Optimization during early Windows 10 deployments after experiencing unexpected WAN traffic. At that time, peer sharing controls were far less granular, making it difficult to limit content sharing to devices within the same network or site. As a result, some organizations chose to disable Delivery Optimization entirely and missed potential bandwidth savings from peer-to-peer content distribution. Today, modern Delivery Optimization policies provide significantly more control through features such as Group mode, Group IDs, subnet-based peer restrictions, bandwidth management settings, and integration with Microsoft Connected Cache. These capabilities help organizations realize the benefits of peer caching while maintaining tighter control over network traffic. Bandwidth throttling: Spoke links are often the bottleneck. Use DOPercentageMaxBackgroundBandwidth to limit Delivery Optimization background downloads to 10% to 25% of available bandwidth during business hours. Configure DOSetHoursToLimitBackgroundDownloadBandwidth to define the hours when those limits apply, then relax or remove the limits outside business hours. Cache retention: Set DOMaxCacheSize to 40% to 50% and DOMaxCacheAge to match your final deployment ring so cached content survives all ring phase days at branches. Branch peers are the only local sources. They need to hold content long enough for the full ring cycle. Hub site: Devices at the hub have direct internet access and also typically have more bandwidth available. Standard cache settings (20% to 30%, 3 days) are usually sufficient. Tip: Combine Peer Caching and Microsoft Connected Cache In star (hub-and-spoke) network topologies, Microsoft Connected Cache (MCC) can deliver the greatest bandwidth savings at central hubs and larger branch offices. By caching frequently requested updates and applications locally, MCC helps reduce the amount of content that must traverse upstream WAN links. You can configure an MCC server directly in your Delivery Optimization policy by specifying: DOCacheHost=<MCC FQDN> When configured, Delivery Optimization continues to prioritize content from nearby peers. If the requested content isn't available from peers, devices will attempt to download it from Microsoft Connected Cache. If the content isn't present in the cache, devices automatically fall back to Microsoft's internet content source. Think of the content retrieval process as a layered approach: Peers → Microsoft Connected Cache → Internet. This hierarchy helps optimize bandwidth usage while maintaining reliable access to updates and applications. Distributed topology With a distributed topology, all locations have their own local internet access. Each site reaches the internet directly, so the WAN penalty for a cache miss is lower. Group boundaries: Set DODownloadMode=2 and set a DOGroupID. The key is that each physical site is its own peer group. DORestrictPeerSelectionBy = 1 (Subnet) is still recommended but less critical because cross-site peer-to-peer traffic is less likely. Bandwidth limits: More relaxed than star. 25% to 50% during business hours is typical since each site has its own internet cache path. Tip: With local internet connectivity and Delivery Optimization Group mode, many locations achieve excellent bandwidth savings with no additional infrastructure. Microsoft Connected Cache adds value primarily at the largest locations (more than 100 devices). Scenario 2. Branch offices with limited WAN Branch offices often see the biggest Delivery Optimization savings. Instead of every device pulling the same update over the WAN, one device can download from the internet and share locally with peers on the subnet. Use DODownloadMode = 2 and assign a unique DOGroupID per branch location to keep peer-to-peer traffic within the branch. Set aggressive background limits (15% to 25% of link speed) to protect line-of-business applications. For very small branches with fewer than 10 devices, or locations where devices are frequently reimaged, consider adding a Microsoft Connected Cache node. A small cache server with a 100 GB drive provides a persistent local source that doesn't depend on any single peer being online. Scenario 3. Mass provisioning and Windows Autopilot During Windows Autopilot bulk provisioning or mass reimaging, many devices request identical content at the same time. Without Delivery Optimization, every device downloads independently from the internet cache, often saturating internet links and extending provisioning times. For environments with repeated content consumption, such as shared devices, labs, and kiosks that get reimaged frequently, peer-to-peer distribution has a structural limitation. After a mass reimage, no device has cached content available to share. This is where Microsoft Connected Cache provides the greatest value. Because the cache node retains content on-premises independent of device state, the first device after a wipe can download from the local cache rather than the internet cache. If you're using peer-to-peer alone, consider staggering reimage schedules so that some devices always have content available to share. Intune already uses Delivery Optimization to distribute Win32 and Microsoft Store apps, so no extra setup is needed beyond the core Delivery Optimization policies. The main tuning is around thresholds and retention. Lower DOMinFileSizeToCache from 10 MB to 5 MB so snaller app installers qualify for peer-to-peer sharing and extend DOMaxCacheAge to 7 days (604800 seconds) to accommodate app deployments that often span a full week. During large provisioning events, be generous with cache resources. Increase DOMaxCacheSize to 50 percent or higher to ensure early devices have room to cache and share content. Set DOMonthlyUploadDataCap to 0 (unlimited) so the first-wave of devices can serve a larger number of peers. Finally, provision devices in stages whenever possible. Even a 15-minute delay between groups gives Delivery Optimization time to build peer availability before the next wave starts. Scenario 4. Devices that move between locations In environments where employees frequently move between locations, isolating peer traffic can be challenging. For example, a device assigned to the Group ID for Branch A may be physically connected at Branch B, causing it to search for peers across the WAN. In this scenario, use DHCP to provide the appropriate DOGroupID and, when applicable, DOCacheHost source for the device’s current location. DOCacheHostSource=1 and set the DHCP Option 235 at the site to the FQDN of the Microsoft Connected Cache. DOGroupIdSource=3 and set the DHCP Option 234 to the GUID for the GroupID. Go further with Microsoft Connected Cache Microsoft Connected Cache is an optional on-premises content cache. It complements Delivery Optimization by providing a persistent local source when peers are unavailable. Tip: Start with Peer-to-Peer Caching First Before deploying Microsoft Connected Cache (MCC), consider optimizing Delivery Optimization peer-to-peer caching. Many organizations achieve substantial bandwidth savings through properly configured download modes, peer groups, cache settings, and deployment rings without introducing additional infrastructure. Peer-to-peer caching is often the simplest and most cost-effective first step because devices can share content directly with one another, reducing internet downloads and WAN utilization across the organization. Microsoft Connected Cache becomes particularly valuable when peer sharing alone cannot fully meet business requirements, such as locations with few devices, frequent device reimaging, limited peer availability, or a need for a persistent on-premises content source. In these scenarios, MCC can complement Delivery Optimization to further reduce bandwidth consumption and improve content availability. Microsoft Connected Cache is most valuable at small locations with few peers, in environments with frequent device resets, or anywhere large content volumes need a guaranteed local source. Devices can find the cache node in two ways: Static (Intune policy): Set DOCacheHost to the FQDN of your Microsoft Connected Cache server in the Intune Settings catalog. Simple, static, works well for single-site deployments. Dynamic (DHCP Option 235): Set DOCacheHostSource = 1 and configure DHCP Option 235 with the MCC server FQDN. Devices discover the correct cache node automatically based on network location. This is the preferred approach for multi-site deployments. When using Microsoft Connected Cache, configure DODelayForegroundDownloadFromHttp to 30 seconds and DODelayBackgroundDownloadFromHttp to 60 seconds. These timeouts control how long Delivery Optimization waits for a local source before falling back to the internet cache; they don’t control download speed. For setup details and hardware requirements, refer to: Release Notes for Microsoft Connected Cache for Enterprise and Education. Troubleshooting tips Slow downloads: The fallback timeout is the most misunderstood Delivery Optimization setting. It controls how long a device waits for a local source before requesting from the internet cache, not download speed. If downloads are slow, check network routing, DNS, and firewall rules. Cache misses: Internet cache Vary headers can prevent content from being cached on the first request. Microsoft Connected Cache respects these headers, which can cause initial cache misses.

AI-accelerated vulnerability discovery and remediation are changing how organizations manage risk. As discussed in Pavan Davuluri’s recent blog, Microsoft is investing across the vulnerability lifecycle to help organizations identify, validate, and respond faster. For IT and security teams, one challenge lies downstream: deploying fixes quickly across endpoints to reduce exposure. Each update needs to be evaluated, piloted, monitored, and enforced across a mixed fleet of devices and apps. Some parts of the estate can move quickly; others cannot because of compliance requirements, approved change windows, and business-critical dependencies. As organizations adopt AI tools and agents across their environment, maintaining a current and hardened endpoint estate becomes increasingly important. In this context, patching becomes an ongoing operational discipline that combines OS, app, and driver updates with compliance enforcement, access control, and security baseline hardening. To keep pace, organizations need a patch strategy that helps in 3 stages: Mitigate: automate updates that can move quickly Assess: prioritize risk based on exposure and severity Contain: enforce compliance and limit exposure Operationalizing a patch strategy requires coordinated capabilities across endpoint management and security tools. Microsoft Intune brings these capabilities together in a single admin center, alongside the broader Microsoft security ecosystem, and is available with qualifying Microsoft 365 subscriptions 1 . In this post, we show how organizations can use these capabilities to build a patch strategy that helps reduce the time between update release and deployment across their endpoint estate. 1. Mitigate: automate updates that can move quickly A patch strategy is not about pushing every update everywhere at once. It’s about identifying the parts of your estate that can move quickly, then using automation, rings, monitoring, and enforcement to help those updates move with confidence. Regulations, approved change windows, validation needs, and business dependencies will shape what’s possible, but the strategy starts by separating repeatable update work from the exceptions that need deeper review. For OS, app, and driver updates that can move quickly, modern tools can help shorten the time between update release and deployment; without manual rollouts, ticket-driven packaging, or reboot disruption. Operationalize in Intune Windows Autopatch orchestrates ring-based update rollouts to reduce manual effort and keep Windows devices current. To help monitor risk, the Autopatch report visualizes how quickly devices apply updates based on the configured deployment cadence. In this report, devices are categorized as current within three days of update release, at risk between three and seven days, and at critical risk beyond seven days, based on the reporting model used by Windows Autopatch. Learn more about ring-based rollout updates or how to reassess Windows OS updates using this report. Hotpatch (enabled by default for 24H2+ in Intune) applies critical updates without requiring a reboot, helping reduce security gaps while keeping users productive. Figure 1: Watch the latest Microsoft Mechanics episode to see how Windows Autopatch and Hotpatch help organizations accelerate update deployment, reduce operational overhead, and keep devices secure. Intune Enterprise App Management (EAM) supports keeping Windows apps current through auto-updates, including the guided upgrade supersedence reporting, which surfaces outdated versions or version changes. EAM auto-updates are now generally available; details are included in the June Intune What’s new blog. Figure 2: Watch how Intune helps you move from update release to deployment to accelerate responses to vulnerabilities with Windows app management. The enhanced application inventory in the All apps page shows the app version installed on each managed Windows device, refreshed multiple times per day on most active devices, helping teams target app-specific vulnerabilities and confirming when fixes have been applied. The Vulnerability Remediation Agent in Security Copilot uses data from Defender Vulnerability Management to prioritize Common Vulnerabilities and Exposures (CVEs) across Intune-managed Windows devices and apps, and provides recommended remediation actions within Intune. The Vulnerability Remediation Agent is currently in public preview, read the blog to learn more. Figure 3: Watch this video to see how the Vulnerability Remediation Agent in Security Copilot, within Microsoft Intune, helps make agentic security easier to adopt and use. Extend across your endpoint estate Apple devices can be configured for automatic OS updates on managed devices, including enforcing updates to the latest version and deploying Background Security Improvement patches through the settings catalog. App updates can be managed by configuring volume-purchased App Store apps to update automatically and deploy updated app packages to keep apps current across macOS, iPhone, and iPad devices. Android devices can be managed using built-in update policies in Intune, including configuring install windows and freeze periods. For corporate Android fleets, Intune also integrates with OEM firmware management solutions - including Zebra LifeGuard Over-the-Air and Samsung E-FOTA - to enable more granular update control. Managed Google Play also supports configurable app auto-update modes, allowing admins to define whether updates install automatically, on Wi-Fi only, or manually. 2. Assess: prioritize risk based on exposure and severity The first step is reducing exposure across the parts of your estate that can move quickly. But not every system, application, or vulnerability can be addressed through broad update deployment. Teams also need a way to determine which risks require immediate action and which ones can be addressed over time. A calendar-based approach can treat every CVE equally. However, it doesn’t account for severity, exposure, or business impact. As AI accelerates vulnerability discovery, this can lead to effort being spent on lower-risk updates while higher-risk updates remain unaddressed. Risk-based service level objectives (SLOs) help bring prioritization to address this challenge. Instead of patching on a fixed schedule, IT and security teams can align response timeframes by severity, moving quickly on actively exploited or critical vulnerabilities, and applying a more measured approach where risk or impact is lower. This stage creates a clearer prioritization of remediation and helps bridge the view between the security teams that identify threats and the IT teams that act on them. Operationalize in Intune and Microsoft Defender The security update status dashboard in Intune provides an aggregated view of update compliance across Windows clients, Windows servers, and Microsoft 365 Apps. It shows overall counts of devices in different states across Intune-endpoints and helps teams identify where remediation should be focused. These status categories reflect how quickly devices apply updates based on a configured deployment cadence and internal SLOs. Figure 4: Security update dashboard showing patch status for Windows clients, servers, and Microsoft 365 apps. Microsoft Defender Vulnerability Management surfaces CVEs, affected devices, vulnerable software, and recommended remediation actions, offering a shared view of risk and progress across IT and security teams. Translate Defender recommendations into targeted Intune actions described in the mitigate section, such as updating software or moving devices through expedited remediation workflows so teams can focus on vulnerabilities that are actively exploited or most likely to affect an organization. Extend across your endpoint estate For Apple devices, use the Apple software update report in Intune to monitor update status across macOS, iOS, and iPadOS. For Android, compliance reporting surfaces devices that fall behind on OS version or security patch level. 3. Contain: enforce patch compliance and limit exposure Even with automated deployments and prioritized triage, gaps can remain. Some devices are unsupported, fall behind, operate on slower deployment rings, and others can’t be patched quickly. A patch strategy needs to focus on including containment for those surfaces. Compliance controls, conditional access, and device hardening act as an always-on safety net that limits risks that can fall through gaps. Compliance policies and Conditional Access can use a patch state as a signal for resource access, preventing non-compliant devices from accessing corporate resources. Security baselines reduce the attack surface by limiting risky defaults and common attack patterns. Together, these controls shift enforcement from a periodic activity to a continuous condition across a fleet. Operationalize in Intune and Defender Use compliance policies in Intune to define what "current" means, including minimum OS build, required update levels, risk status, and encryption state. Use Conditional Access (managed in Microsoft Entra, accessible from the Intune admin center) to control access to company resources based on user and device health. Combined with threat signals from Microsoft Defender, these policies help prevent non-compliant devices from accessing corporate resources. Use Microsoft Defender Vulnerability Management and Microsoft Security Exposure Management insights to identify exposed assets, prioritize remediation, and apply recommended protections where patching must move more slowly. Apply Intune security baselines to establish Microsoft-recommended configurations on Windows devices, such as disabling risky defaults, blocking common attack techniques, and reducing configuration drift. Watch this demo on security baselines being applied in the Zero Trust workshop. Use attack surface reduction policies in Intune to deploy Microsoft Defender for Endpoint protections, such as ASR rules and network protection, that help block common attack techniques on devices that can't be patched right away. Figure 5: Watch this Demo on how you can manage devices and implement Conditional Access with Intune. Extend across your endpoint estate Compliance policies and Conditional Access controls apply across Windows, macOS, iOS/iPadOS, and Android. Intune app protection policies extend compliance requirements and data protections to managed apps used for work on personal devices and add an additional layer of data protection on corporate devices. Use the settings catalog and configuration profiles to apply the same hardening intent on macOS, iOS/iPadOS, and Android, reducing configuration drift across platforms. Stay ahead with a patch strategy As vulnerability discovery and response continue to accelerate, organizations need an operational strategy that balances speed, risk, and resilience. By automating updates where possible, prioritizing remediation based on exposure, and limiting exposure through compliance and security controls, teams can reduce risk across their endpoint estate. Intune helps simplify this approach by bringing these capabilities together alongside the rest of your Microsoft security tools and ecosystem.
