Microsoft has acknowledged a significant bug affecting Windows 11 and Windows 10 PCs that may prevent users from successfully resetting or recovering their systems. An out-of-band update, KB5066189, was released to address this issue. Users experiencing failures with the "Reset my PC" feature or the "Fix problems using Windows Update" option are advised to install this update. The reset issue does not affect systems running Windows 11 version 24H2, although some users have reported that SSDs and HDDs may become invisible to the operating system in this version, making data unrecoverable.

The Windows 11 KB5063878 update, released on August 12th, has raised concerns about potential corruption issues affecting Solid State Drives (SSDs), particularly in Japan. Users have reported that files and drives became inaccessible after installing the update. The update was intended to reset device certifications for Windows Secure Boot, but user experiences indicate that substantial data writing to the drive can lead to it disappearing from the operating system. A reboot may result in Windows being unable to read the partition, and the SSD’s SMART features may become non-functional. A Japanese PC enthusiast noted that the likelihood of system file corruption increases when approximately 50GB of data is written to a drive that is at least 60% full. Specific SSD brands, including Corsair, Phison, Fikwot, and Maxio, have been highlighted as potentially more vulnerable. It has been suggested that the update may introduce a bug affecting long sequential writes, causing the operating system to lose track of the drive. Users are advised to back up data and consider pausing updates if they have not yet installed KB5063878, while those who have should keep updates enabled to receive fixes promptly.

Microsoft has resolved a significant bug affecting Windows users since August 12, which hindered the migration from Windows 10 to 11 and caused various issues, including installation errors and data corruption. The upgrade issue was particularly problematic for users transitioning from Windows 10 version 1809 to Windows 11 22H2 and 23H2, as well as for Windows Server upgrades, with many encountering error code 0x8007007F. Microsoft confirmed the fix on August 18, although it was available as early as August 15. The latest versions, Windows 11 version 24H2 and Windows Server 2025, were not affected by these issues. Users are urged to upgrade from Windows 10 before October 14 to avoid losing essential security updates.

Microsoft's security update for Windows 11, KB5063878, has been linked to SSD failures during intensive file transfers. A user reported that their SSD disappeared while updating a game, particularly when transferring data over 50GB on a drive more than 60% full. Rebooting the system temporarily restored the SSD's visibility, but the issue recurred. A specific Western Digital SA510 2TB SSD was reported as irretrievable even after a restart. Other users have experienced similar problems, including a SanDisk Extreme Pro M.2 NVMe SSD becoming inaccessible after a large update. While the issue has been noted by multiple users, it does not appear to be widespread, and there is no definitive link established between the updates and the failures. Users are advised to exercise caution with large file transfers on systems with the latest update.

Microsoft has lifted the compatibility hold that previously prevented some users of Easy Anti-Cheat from upgrading to the Windows 11 2024 Update due to issues causing unexpected restarts and blue screen of death (BSOD) errors. An emergency update (KB5063060) was released on June 11 to address these compatibility issues. As of July 24, 2025, eligible devices can now install Windows 11, version 24H2 via Windows Update, although users may see a warning about an incompatible version of Easy Anti-Cheat. Microsoft confirmed that older versions of Easy Anti-Cheat will not trigger a BSOD unless activated by a game. Additionally, a safeguard hold imposed in October for Intel Alder Lake+ and vPro systems was lifted in March after resolving related issues. Other compatibility holds affecting AutoCAD and Safe Exam Browser users have also been removed.

Microsoft released an emergency update to address a bug affecting Azure virtual machines (VMs) that prevented them from launching when the Trusted Launch setting was disabled while Virtualization-Based Security (VBS) was enabled. This issue emerged during the July Patch Tuesday security updates and impacted Windows Server 2025 and Windows 11 24H2, specifically affecting VMs using version 8.0 with VBS provided by the host. The root cause was identified as a secure kernel initialization issue, which has been fixed with the KB5064489 out-of-band update. Administrators are advised to check if their VMs are created as "Standard" and if VBS is enabled. If affected, they should install the out-of-band update instead of the July 8th KB5062553 Patch Tuesday update and consider using the Trusted Launch security feature. Microsoft has also updated Windows Server 2025 VM images to include the latest cumulative update addressing this bug.
