Hi, I am having and issue with Windows Server flighting on domain controllers. On my DC new builds are never offered and the Windows Insider Program page in settings will say we can't reach this page right now. If I demote the DC flighting works again and the build is offered. Is this by design that flighting is disabled or is there something that I can do to try to troubleshoot this? Thanks in advance. Kevin73Views0likes2Comments

Hello Windows Server Insiders! We welcome you to try Windows Server vNext Datacenter: Azure Edition preview build 29659 in both Desktop experience and Core version on the Microsoft Server Operating Systems Preview offer in Azure. Azure Edition is optimized for operation in the Azure environment. For additional information, see Preview: Windows Server VNext Datacenter (Azure Edition) for Azure Automanage on Microsoft Docs.

Hello Windows Server Insiders! Today we are pleased to release a new build of the next Windows Server Long-Term Servicing Channel (LTSC) Preview that contains both the Desktop Experience and Server Core installation options for Datacenter and Standard editions and Azure Edition (for VM evaluation only). Branding remains Windows Server 2025 in this preview - when reporting issues please refer to Windows Server vNext preview. Build 29531 established a new Server preview baseline build. Please perform a clean install of Build 29531 (or later) using the installation media linked below. Please note: Upgrades from Windows Server vNext preview builds older than 29531 are not supported. We encourage all Windows Server vNext preview users to perform a clean install using 29531 or later to successfully upgrade to future Windows Server vNext preview builds. While upgrades from earlier Windows Server previews (Build 26525 and older) are not technically blocked by setup.exe, a number of known issues have been identified related to upgrades necessitating the establishment of a new baseline build for our Server vNext Preview Program. The new baseline build (29531) will not be Flighted due to upgrade issues. Flighting support resumed with preview build 29550 or later. What's New Trusted Launch for virtual machines (TVMs) on Windows Server—a security feature you can enable when creating Generation 2 VMs. This initial preview supports TVMs with Secure Boot, vTPM, and vTPM state protection (at rest), managed via PowerShell. ⚠ Not supported in this release: Moving TVMs to another server TVMs in failover clusters or Hyper-V Replica Boot integrity verification TVMs in Windows Admin Center (WAC) Instructions 1. Install the latest ServerInsider preview build. 2. Enable Hyper-V (restarts the server): Install-WindowsFeature -Name Hyper-V -IncludeManagementTools -Restart 3. Set the registry keys: New-Item -Path "HKLM:\SOFTWARE\Microsoft\AszIgvmAgent" -Force New-ItemProperty -Path "HKLM:\SOFTWARE\Microsoft\AszIgvmAgent" -Name "TvmWinServer" -Value 1 -PropertyType DWord -Force 4. Enable Trusted Launch: Enable-WindowsOptionalFeature -Online -FeatureName "IsolatedGuestVm" -NoRestart 5. Verify IGVmAgent is running (should show Running): Get-Service -Name "IGVmAgent" If it isn't running, report the issue with the IGVmAgent and IGVmSystem Operational logs (Event Viewer → Applications and Services Logs → Microsoft → Windows). 6. Create an external virtual switch (if needed): (Get-VMSwitch | Where-Object { $_.SwitchType -eq "External" }).Name 7. Create the TVM. With an existing Gen 2 VHDX: New-VM -Name <VMName> -Generation 2 -GuestStateIsolationType TrustedLaunch -SwitchName <switch> -VHDPath <path to vhdx> -Path <config path> Or with a new VHD, then attach a Gen 2–compatible guest OS ISO: New-VM -Name <VMName> -SwitchName <switch> -NewVHDPath <new VHD path> -NewVHDSizeBytes 40GB -Generation 2 -GuestStateIsolationType TrustedLaunch -Path <config path> Add-VMDvdDrive -VMName <VMName> -Path <Guest OS ISO path> Ensure the DVD drive is first in the firmware boot order so the VM boots from it. 8. Verify isolation type (should return TrustedLaunch): (Get-VM -Name <VMName>).GuestStateIsolationType 9. Verify guest state protection: Stop the IGVmAgent service and restart the VM—without IGVmAgent running, a Trusted launch VM with guest state protection won't start. For more information, please review our blog post: Announcing Trusted Launch for Virtual Machines for Windows Server Insiders | Microsoft Community Hub Quick Machine Recovery available in Windows Server vNext Insider Previews. Quick machine recovery (QMR) is now available for Server vNext Insiders to test. This feature enables the recovery of Windows Server devices when they encounter boot critical errors that prevent them from booting. QMR can automatically search for cloud‑based remediations to recover from widespread boot failures significantly reducing the burden on IT administrators when multiple devices are impacted. This supports the goals of the Windows Resiliency Initiative by enabling applicable fixes to be delivered through trusted Windows Update to restore affected devices, helping reduce downtime and minimize manual recovery efforts across enterprise environments. This feature is currently enabled in the latest Server vNext Insider builds for customers to experience test mode. A Group Policy option to enable or disable the feature will be introduced in upcoming builds to provide additional administrative control. To simulate the quick machine recovery experience, use the following commands from an elevated command prompt: Enable test mode: reagentc.exe /SetRecoveryTestmode Configure Windows to boot to Windows Recovery Environment on the next boot: reagentc.exe /BootToRe Reboot your device.The system goes through autoremediation of a simulated crash safely and reboots back to Windows Server. For more information, please review Quick machine recovery (QMR) and Windows Resiliency Initiative. When providing feedback using Feedback hub, please select QMR from the Recovery and Uninstall category in the app. NVMe-over-Fabrics (NVMe-oF) extends the NVMe protocol—originally designed for local PCIe-attached SSDs—across a network fabric. Instead of using legacy SCSI-based protocols such as iSCSI or Fibre Channel, NVMe-oF allows a host to communicate directly with remote NVMe controllers using the same NVMe command set used for local devices. In this Insider build, Windows Server supports: NVMe-oF over TCP (NVMe/TCP), allowing NVMe-oF to run over standard Ethernet networks without specialized hardware. NVMe-oF over RDMA (NVMe/RDMA), enabling low-latency, high-throughput NVMe access over RDMA-capable networks (for example, RoCE or iWARP) using supported RDMA NICs. For more information, please visit: Introducing the Windows NVMe-oF Initiator Preview in Windows Server Insiders Builds | Microsoft Community Hub ReFS Boot is enabled for Windows Server vNext preview builds. Known Limitations ReFS Boot systems create a minimum 2GB WinRE partition. When WinRE cannot be updated due to space constraints, the system may disable WinRE. Disabling WinRE does not remove the partition. If the WinRE partition is deleted and the boot volume is extended over it, this operation is unrecoverable without a clean install. For more information, please visit: Resilient File System (ReFS) overview | Microsoft Learn Feedback Hub app is available for Server Desktop users! The app should automatically update with the latest version, but if it does not, simply Check for updates in the app’s settings tab. Known Issues A race condition in the TLS hybrid key exchange implementation may cause the LSASS service to crash when hybrid groups are negotiated by a TLS server. To avoid this issue until the fix is released, please disable hybrid groups (X25519_MLKEM768, SecP256r1_MLKEM768, SecP384r1_MLKEM1024) using TLS cmdlets or Group Policy, as outlined here. Server Core Upgrades and AppCompat FOD: Enabling AppCompat FOD after reinstall may fail due to legacy 3rd-party license compatibility issues on Server Core devices. Server Core users may be unable to install the latest AppCompat FOD after upgrading to build 29574. This appears to be limited to Server Core installations with 3rd-party application licenses that fail compatibility checks after upgrade. This will be addressed in a future build. Upgrading from older builds of Windows Server vNext previews (26525 or older) are not supported. Please perform a clean install of build 29531 or later. Users may experience failures when attempting to upgrade from earlier previews (build 26525 and older). VMs may fail to upgrade or start after upgrade from older preview builds impacting live migration and failover cluster scenarios. Download Windows Server Insider Preview (microsoft.com) Flighting: The label for this flight may incorrectly reference Windows 11. However, when selected, the package installed is the Windows Server vNext update. Please ignore the label and proceed with installing your flight. This issue will be addressed in a future release.

3 days ago I tried opening Quick Assist to getting a %d error code. I have reset my computer twice, tried creating a local account as administrator and tried opening Quick Assist that way, still same error persists. When I go to Installed apps > Microsoft Edge WebView2 Runtime, when I click on the 3 dots next to it the options are not white they are a grey colour and doesn't allow me to click on them. My OS Build 29639.1000 and my Windows Edition is - Windows 11 Home Insider Preview and the version is - Dev Also doesn't allow me to log into any PC Xbox accounts as well. Any help would be very appreciated.324Views0likes1Comment
