A security researcher’s routine Copilot query revealed a startling blind spot in Microsoft’s logging: under certain prompts, Copilot could return file summaries without leaving the expected Purview audit entry — and, according to the researcher, Microsoft quietly rolled out a fix without issuing a CVE or proactively notifying customers. Background Microsoft Copilot is now embedded across the Microsoft 365 stack — from Outlook and Word to Teams, SharePoint and the suite of Copilot-hosted...

Microsoft pushed an emergency, out‑of‑band cumulative update on August 19, 2025 to repair a high‑impact regression that broke Windows’ built‑in reset and recovery flows — a failure that left some users and IT operations teams unable to run “Reset this PC,” the cloud‑reinstall Fix problems using Windows Update, or complete MDM‑initiated RemoteWipe jobs until fixes were installed. Background / Overview The incident began after the August 12, 2025 Patch Tuesday cumulative updates were broadly...

Microsoft has started rolling out a meaningful update to the Copilot app for Windows Insiders that brings semantic file search (on Copilot+ PCs) and a redesigned Copilot homepage with quicker access to recent apps, files, and Vision-driven guidance — a staged release that promises faster, more natural file discovery while keeping most heavy AI work on-device. Background Microsoft has been steadily folding more AI capabilities into Windows 11 under the Copilot and Copilot+ initiatives for...

Microsoft has shipped Windows 11 Insider Preview Build 27928 to the Canary Channel, a fast-moving test drop that continues Microsoft’s phased rollout of Copilot-driven experiences, UI refinements, and a suite of stability fixes — but it also brings the usual Canary trade-offs: experimental features, privacy trade-offs for Copilot capabilities, and a handful of platform-level caveats Insiders and IT pros should treat carefully. Background / Overview Windows Insider Canary Channel builds are...

Windows Insiders received a fresh Canary-channel drop today as Microsoft released Windows 11 Insider Preview Build 27928, a focused maintenance and settings consolidation update that both cleans up a handful of pressing stability issues and continues the steady migration of legacy Control Panel capabilities into the modern Settings app. Background What the Canary Channel is — and why it matters The Canary Channel remains the experimental front line of Windows development where the newest...

Microsoft has begun rolling out a targeted update to the Copilot app on Windows that brings semantic file search to Copilot+ PCs and introduces a redesigned Copilot homepage for Windows Insiders, marking a clear step toward tighter on‑device AI integration in Windows. rr channel updates over the summer have steadily introduced Copilot‑related features tied to the company’s Copilot+ PC initiative. These features are being enabled gradually and are frequently gated by device capabilities...

Microsoft released Windows 11 Insider Preview Build 27928 to the Canary Channel on August 20, 2025, and the flight is a concise but telling example of what the Canary track is for: low-latency platform experiments, targeted rollouts, and rapid iterations that can both surface neat usability gains and expose rough edges that still need fixing. This build doesn’t introduce headline features, but it tightens a number of behind‑the‑scenes issues, continues the migration of legacy Control Panel...

Microsoft has begun rolling out an update to the Copilot app on Windows that brings semantic file search to Copilot+ PCs and a redesigned Copilot homepage to Insiders, delivering tighter, AI-driven file discovery and faster access to recent apps, files, and guided help directly inside the Copilot experience. This staged release—delivered via the Microsoft Store to Windows Insiders—aims to make finding documents, images, and settings feel conversational while keeping the heavy lifting...

Microsoft’s August update cycle produced an unexpected and dangerous side effect: built‑in recovery tools stopped working on numerous Windows client releases, and Redmond pushed emergency, out‑of‑band (OOB) cumulative updates — KB5066189, KB5066188 and KB5066187 — on August 19, 2025 to restore Reset, cloud recovery and MDM remote‑wipe functionality. These fixes supersede the problematic August rollups and include servicing‑stack updates; Microsoft recommends installing the OOB packages if...

Microsoft’s Snipping Tool for Windows 11 is getting a practical — if incremental — upgrade: a new window mode for screen recording that lets you pick a single application window as the recording region instead of drawing a freeform rectangle around the desktop. The change is shipping to Windows Insiders in Canary and Dev channels as part of Snipping Tool version 11.2507.14.0 (rolled alongside Windows Insider Preview Build 27924), and it is designed to reduce post-capture cropping and...

Microsoft and SSD vendors have opened a coordinated investigation after multiple independent testers and users reported that the August Windows 11 cumulative update (KB5063878, OS Build 26100.4946) can, in rare but reproducible cases, cause some SSDs to stop responding or “vanish” during sustained, large write operations — sometimes leaving partitions corrupted or data inaccessible. eed KB5063878 (OS Build 26100.4946) as the regular August cumulative update for Windows 11 24H2. The update’s...

Hotpatch-ready fleets start with one infrastructure choice: enable Virtualization‑based Security (VBS) correctly and at scale — doing so is the single most important step to ensure your Windows devices are eligible for Microsoft’s hotpatch model and to materially reduce reboot-driven downtime for security updates. This article walks through the rationale, the exact prerequisites, the step‑by‑step configuration options for mass enablement (Intune, CSPs, Group Policy, registry), Arm64-specific...

Hotpatch readiness is no longer an optional optimization for modern Windows fleets — it’s a foundational capability for any organization that values continuous uptime, rapid security response, and simplified update logistics. Enabling Virtualization‑based Security (VBS) at scale is the single most important operational step to unlock hotpatch delivery across managed devices. The following feature unpacks the technical requirements, step‑by‑step rollout guidance, platform and licensing...

Hotpatching’s promise — apply security fixes without forcing reboots — hinges on one non‑negotiable platform capability: Virtualization‑Based Security (VBS). For organizations preparing fleets for hotpatch delivery, enabling VBS at scale is the single most important operational task, and it’s also the step that creates the most surprises if not planned carefully. This feature‑length guide explains what VBS requires, how to enable and validate it across thousands of endpoints, how VBS ties...

Microsoft pushed an emergency, out‑of‑band patch on August 19, 2025 to repair a serious regression introduced by its August Patch Tuesday rollups that could prevent Windows’ built‑in recovery flows — Reset this PC, the Fix problems using Windows Update cloud reimage, and certain RemoteWipe (RemoteWipe CSP) operations — from completing, and system administrators and home users should treat the matching fixes (KB5066189, KB5066188, KB5066187) as high‑priority for affected devices. Background...

Valve’s long-rumoured set-top box, codenamed Fremont, has reappeared in public testing data — this time in Geekbench — and the leaked entry paints a picture of a TV-focused SteamOS device in active development that, for now, was tested running Windows 11 Pro rather than a finished SteamOS image. Background Valve’s “Fremont” codename first surfaced in kernel commits and driver traces late in 2024, when references to HDMI CEC and an AMD-based development board hinted that Valve was working on...

Microsoft pushed emergency out‑of‑band updates on August 19, 2025, to repair a critical regression that prevented Windows’ built‑in reset and recovery tools from completing — a problem introduced by the August 12, 2025 Patch Tuesday security rollup that caused attempted “Reset this PC” and cloud recovery operations to start, reboot, and then immediately roll back without finishing. Background The August 2025 cumulative security updates were deployed through the regular monthly channel on...

The NFL and Microsoft announced a multiyear extension of their long-running technology partnership that formally moves the league into an AI-first operational phase — bringing Microsoft Copilot, Azure AI services, and an expanded Surface device rollout onto sidelines, into scouting workflows and into stadium operations.
