Microsoft Copilot 365 Personal Premium limits
In my Copilot Notebook, I deliberately loaded 20 PDF files in order to test Copilot’s grounding behavior across the full set of available references. At the time this testing setup was created, 20 references represented the effective grounding limit described for Copilot Notebooks, meaning that these references were expected to form the source base used by Copilot when generating grounded responses. The references consisted of fully functional, original academic textbooks containing relevant and up-to-date scientific information, mostly published within the last ten years. Importantly, the sources do not differ from one another in terms of accessibility, file type, availability, or how they were added to the notebook. They are all PDF files, they are all available in the same environment, and there is no obvious difference in access conditions that would explain why some are consistently used while others are repeatedly treated as inaccessible, unavailable, summarized, or skipped. The purpose of the test was therefore not simply to see whether Copilot could access 20 files, but whether it could actually ground its answers in the complete reference set when explicitly instructed to analyze all available sources. Despite this, in approximately 99.9% of my tests, Copilot appears to ground its responses in only 3 to 5 of the 20 available references, often repeatedly using the same documents. When I ask what happened to the remaining sources, Copilot gives different explanations. Sometimes it says that it does not have access to certain files. Sometimes it says that it only received a summary of the file. Sometimes it says that a step involved in retrieving or processing the information failed. The way Copilot explains this often makes it sound as if access to the uploaded files depends on some external or intermediate system, rather than being something Copilot itself can directly control. This is difficult to understand from a user perspective because the files are already uploaded into the Copilot environment and were specifically provided as source material for analysis. The practical result is that a task explicitly requesting analysis of 20 sources often produces an answer based on only 3 to 5 of them. For academic or research use, this is a serious limitation. If 15 to 17 out of 20 carefully selected sources are not actually examined, then the final synthesis cannot realistically represent the full source base. This also creates uncertainty about what Copilot means when it claims to have used the provided materials. My question to Microsoft is: Is there a technical limit on how much information Copilot can actually retrieve, open, and analyze from uploaded files during a single task or session? If such a limit exists, what is that limit? And why, when 20 valid PDF sources are uploaded and Copilot is explicitly instructed to analyze all of them, does it so often appear to open only 3 to 5 files, while describing the others as inaccessible, summarized, or unavailable because some retrieval step failed?Microsoft Copilot 365
To Microsoft: Serious Concerns Regarding the Actual Capabilities of Microsoft Copilot Microsoft, After 12 consecutive days of intensive testing of Microsoft Copilot, for approximately eight hours per day — around 96 hours of practical use in total — I have serious concerns about the accuracy of the way Copilot's functions and capabilities are described and presented by Microsoft. What I have observed in actual use is repeatedly and substantially different from what the product is presented as being capable of doing. This conclusion is not based on a single unsuccessful prompt, an isolated error, or a short test. It is based on repeated testing over many days, involving continuous academic, analytical, document-based, and multi-step tasks. One of the most serious problems is Copilot's inability to reliably maintain and use conversational context even within the same active session. For example, Copilot can generate a substantial piece of text and, in the immediately following interaction, claim that it cannot see or access that same text. It may ask the user to provide again information or content that Copilot itself generated only one response earlier. This makes it impossible to rely on the system for genuine sequential work. During testing, the same general problem has appeared in different forms: Copilot fails to return reliably to earlier tasks, loses access to information already established within the conversation, fails to connect consecutive instructions, and sometimes behaves as though previous parts of the same active session do not exist. This is particularly serious when Copilot is used for academic or research work. A workflow may require the system first to generate or analyse material, then classify it, compare it with another part of the work, identify its sources, reorganise it, and finally continue developing it. If Copilot cannot reliably access the result of the immediately preceding step, such a workflow becomes fundamentally unreliable. After approximately 96 hours of direct testing, it is increasingly difficult to regard these problems simply as occasional technical limitations. The discrepancy between Microsoft's descriptions of Copilot and the behaviour actually observed during sustained use is substantial enough to raise a much more serious question: whether the functions and capabilities attributed to Copilot in Microsoft's product descriptions accurately represent what the system can actually and reliably do in normal use. From the user's perspective, the current experience creates the impression that Microsoft's claims about Copilot's capabilities are misleading. A capability should not be considered a genuine product capability merely because the system can occasionally perform it under favourable conditions. If a feature is presented to users as part of the product's functionality, users should reasonably be able to expect that functionality to operate consistently enough to be relied upon. After 12 days of testing, that has not been my experience. The difference between the advertised or described capabilities and the actual behaviour of Copilot is not minor. In several fundamental areas — particularly conversational continuity, access to previous work within the same session, multi-step task execution, and reliable reuse of previously generated content — the practical experience does not correspond to the expectations created by Microsoft's descriptions of the product. After nearly 100 hours of testing, I am therefore questioning not simply the quality of Copilot, but the accuracy and transparency of Microsoft's representation of what Copilot is actually capable of doing. If Microsoft describes Copilot as possessing capabilities that repeatedly cannot be reproduced in sustained real-world use, then the issue is no longer merely whether Copilot occasionally makes mistakes. The issue is whether users are being given an accurate representation of the product they are being asked to use and pay for.
Bitlocker key requested on the boot, but I don’t have any key
My laptop (Windows 10, version 22H2, build 19045), that I have been using more than 6 years already, suddenly started asking for the BitLocker recovery key at startup, which is blocking access to the system entirely. What I've already checked/tried: - Checked account.microsoft.com/devices/recoverykey while signed in with my Microsoft account, no key appears for this device. - Contacted Microsoft Support directly, they said they can no longer assist with Windows 10 issues and suggested posting here instead.

SCCM PXE Boot Deep Dive – Backend Flow & DP Migration I recently worked on a Distribution Point migration and noticed PXE requests were still routing to the old DP due to DHCP/IP helper configuration. I put together a deep dive explaining: PXE flow (DHCP and TFTP sequence) Role of Distribution Points What changes during DP migration Common failure points One key takeaway: PXE issues are almost always network and routing related, not SCCM itself. Curious how others are handling PXE in large environments. Are you standardizing on IP helpers or still using DHCP options?

We’re excited to share the latest updates to these security and governance tools, designed to help you: Gain a unified view of key security and governance features as a Copilot/IT admin Block sensitive data from Copilot processing or sent as web queries Address oversharing through automation and greater visibility The latest security and governance updates introduce the following tools and features: Purview value integrated in the Microsoft 365 admin center Purview Data Loss Prevention for Microsoft 365 Copilot to safeguard prompts Purview Data security posture management Data risk assessments: item-level investigation and remediation SharePoint Advanced Management (SAM) Content management assessment SAM Permission report for a given user SAM Agent insight report SAM Catalog management SAM Delegating control to site administrators allows site admins to manage Restricted access control (RAC) and Restricted content discovery (RCD) SharePoint Admin Agent Microsoft Baseline security mode Be sure to watch the Ignite session BRK 293 - From oversharing to oversight for more details and demos of many of these new capabilities! Unified view of key security features As a Copilot and IT admin managing the security and governance of Copilot, you need a unified view to see key security and governance features and take actions. At Ignite 2025, we announced that Microsoft Purview value is now integrated directly into the Microsoft 365 admin center (MAC). Now available in Public Preview. The Copilot overview page now offers a Security tab, where you can click on cards to prevent data leakage, manage data oversharing, and strengthen data compliance, directly in the MAC. Block sensitive data from processing Many of you have expressed concerns about sensitive data being processed by Copilot or sent as web queries through a web search. Last year, we announced Microsoft Purview Data Loss Prevention (DLP) for Microsoft 365 Copilot (now Generally Available) to block Copilot from processing files and email with specific sensitivity label. This year, we are thrilled to extend the capability of DLP for Copilot to safeguard prompts that contain sensitive data. Now available in Public Preview. We are also excited to share that Purview DLP for Copilot prompt is available to all users of Microsoft 365 Copilot and Copilot chat! Purview DLP for Copilot prompt provides real-time control to help you mitigate data leakage and oversharing risks. It prevents Microsoft 365 Copilot, including pre-built agents in Microsoft 365 Copilot, and Microsoft 365 Copilot Chat, from returning a response when the prompt contains sensitive data. This feature helps to ensure sensitive data is not used for internal grounding or sent through web searches. Microsoft Purview Data Loss Prevention for Microsoft 365 Copilot to safeguard prompts blocking responses to questions around Project Wingtip, as Project Wingtip is on the organization’s sensitive information block list Automation and visibility to address oversharing As part of Microsoft’s commitments and controls, Copilot responses only contain data the user has permission to access, but oversharing can still happen regardless of Copilot use. Oversharing happens when an employee has been granted access to information and files that aren’t necessary for them to do their job. It’s generally an accidental oversight occurring when users share files too broadly, or when files aren’t protected in a way that persists regardless of location. To help customers address oversharing for a Microsoft 365 Copilot deployment, we published the Oversharing blueprint, powered by two powerful tools: Microsoft Purview, and SharePoint Advanced Management - included in your Microsoft 365 Copilot license. Last year we introduced Microsoft Purview Data security posture management for AI Data risk assessment to address oversharing concerns. This year, we expanded Data risk assessments to include item-level investigation and remediation. Now, in addition to identifying sharing links across SharePoint sites, this enhanced capability enables bulk remediation by allowing admins to remediate or disable overshared links at scale. This helps organizations proactively reduce data exposure, strengthen compliance posture, and ensure sensitive files are only accessible to the right people. Now available in Public preview. SharePoint Advanced Management (SAM), included in your Microsoft 365 Copilot license, concentrates on helping you manage content sprawl and clutter, control permissions and content access, and automate housecleaning chores like making sure all your sites have owners, content is attested on a continuous basis, and provides targeted audit capabilities by tracking changes in the tenant configurations. We’re excited to share these new SAM features: Content management assessment evaluates and improves content management with a single click to identify content risks, ensure compliance, and maintain data integrity. Generally Available. Permission report for a given user provides a detailed overview of all SharePoint and OneDrive access points, highlights oversharing risks, and enables admins to quickly identify and fix risky permissions across the organization for a given user. Generally Available. Agent insight report shows how agents interact and access SharePoint sites and OneDrive accounts, and allow admins take governance actions to manage these agents. Generally Available. Catalog management defines organizational content clusters for targeted actions and automatically groups SharePoint sites using existing sites and user properties to enable governance with precision and at scale. Available in Public Preview. Delegating control to site administrators allows site admins to manage Restricted access control (RAC) and Restricted content discovery (RCD). Available in Public Preview. We’ve also heard many of you request support in working with the breadth of admin tools, reports and capabilities available in SharePoint—so we were especially excited to announce SharePoint Admin Agent, designed for administrators that are tasked with the responsibility of insuring that their organizational content is governed properly in the AI era, with the help of AI. Now available in public preview. The SharePoint Admin Agent removes the need for you to know what SAM reports to trigger, how to read the reports, what actions to take. Now all you need to know is what problem you are trying to solve. The SharePoint Admin Agent will be equipped with skills to help you manage permissions, storage, lifecycle and access to start with, but we have much more planned for the future. Baseline security mode The adoption of AI can accelerate the ability for malicious actors to exploit configuration gaps, specifically legacy configurations that can be the most vulnerable, in your enterprise environment. To support security administrators with this challenge, we introduced Baseline security mode, which applies Microsoft-recommended security settings across Office, SharePoint, and Teams to standardize protections across your deployments, so you can more easily identify gaps and reduce risk. Baseline security mode, included with your existing Microsoft 365 license, is Generally Available for Microsoft 365 and Entra. It allows you to: Act on tailored recommendations with preconfigured defaults that protect against known vulnerabilities from legacy configurations and emerging AI risks exploiting them, helping you keep pace with the rapidly evolving threat landscape and helps to ensure that security protections are current. Adopt changes safely and test configurations safely in simulation mode before rollout, making adoption straightforward, mitigating the risk of misconfiguration and helping organizations stay ahead of evolving threats. Take advantage of built-in protection and benefit from purpose-built integration, as BSM is optimized for Microsoft 365, and updated regularly to help deliver ongoing security enhancements. To learn more on how to get started with Microsoft Baseline security mode, read our Insider Track blog and Learn doc. Closing As we continue to enhance security and governance capabilities, Microsoft is committed to building trust with you, our customers, by equipping you with robust tools to effectively manage Copilot and agents. By delivering security and governance capabilities in Microsoft 365 Admin Center, Microsoft Purview, and SharePoint Advanced Management, we empower administrators to maintain transparency, security, and compliance in your Microsoft 365 environments. These innovations ensure your most valuable data is protected and provide your organization with the confidence to collaborate securely in an AI-powered workplace.
