Microsoft is alerting users about a critical issue affecting reset and recovery operations in select versions of Windows. Following the August 2025 security updates, users attempting to reset their PCs or recover data through various Windows functionalities might encounter failures.
Emergency Update Response
In response, Microsoft has rolled out an out-of-band (OOB) emergency update aimed at addressing this glitch. The affected versions include Windows 11 versions 23H2 and 22H2, as well as Windows 10 builds that are supported beyond October. However, Windows 11 24H2 remains unaffected by this issue.
Released on August 20, the emergency update is intended to replace the standard August security update. Microsoft strongly advises users to prioritize this OOB update to circumvent the potential operational disruptions associated with reset and recovery processes.
Details of the Affected Versions
- Windows 11 23H2: Identified as KB5066189, it corresponds to OS Builds 22621.5771 and 22631.5771.
- Windows 10: Documented as KB5066188, the update applies to OS Builds 19044.6218 and 19045.6218.
It is imperative that users implement the updates due to the potential failures in resetting procedures, whether conducted manually via the 'Reset this PC' utility, through Windows Update fixes, or using RemoteWipe CSP.
Installation and Functionality
The installation of the emergency update necessitates a system restart and effectively supersedes any previously installed updates for the impacted versions. Users concerned about security can rest assured as the OOB update doesn't include additional security patches beyond those already incorporated in the August 2025 security update.
This strategic move by Microsoft underscores the company’s commitment to maintaining system integrity and operational reliability for its extensive user base. As always, users are encouraged to keep their systems up to date with the latest available patches and updates to ensure smooth functionality.
