Microsoft has acknowledged that its 12 Aug. Patch Tuesday security releases—identified as KB5063875 and KB5063709 for Windows 10 and KB5063878 for Windows 11—can silently disable key recovery features. After installing the updates, attempts to use the built-in “Reset this PC” option, the “Fix problems using Windows Update” function, or enterprise RemoteWipe commands fail without completing. The defect affects Windows 10 22H2 and long-term-service channel editions, as well as Windows 11 22H2 and 23H2; Windows 11 24H2 and Windows Server builds are not impacted. The malfunction was added to Microsoft’s Windows Release Health dashboard on 18 Aug. following widespread reports from administrators. Because the flawed patches also contain critical security fixes, the company urged customers not to uninstall them while it prepared a remedy. Redmond released an out-of-band correction within 48 hours. The cumulative updates KB5066188 for Windows 10 and KB5066189 for Windows 11, published 19–20 Aug., replace the original packages and restore reset and recovery capabilities. Users who have already applied the August security patches are advised to install the new build from the Optional Updates section; those yet to update should deploy only the corrected version. Separately, some users report that update KB5063878 can cause certain solid-state drives to drop offline during large write operations. Controller supplier Phison said it is investigating the storage issue with Microsoft and warned that falsified documents circulating online overstate the problem. Microsoft has not formally confirmed the drive-failure reports.
