In the latest round of updates from Microsoft, the October Patch Tuesday release has brought with it a mix of enhancements and a few unwelcome bugs. While the update successfully addressed over 170 security vulnerabilities, it has also introduced a notable glitch that impacts users relying on the Windows Recovery Environment (WinRE) for troubleshooting boot issues.
Following the installation of the security update on October 14, 2025 (KB5066835), users have reported that USB devices, including keyboards and mice, are rendered non-functional within WinRE. This limitation hinders navigation through recovery options, although these devices continue to operate normally within the Windows operating system itself. The issue affects Windows 11 versions 25H2 and 24H2, as well as Windows Server 2025. Microsoft is aware of the problem and is actively working on a resolution, expected to be rolled out shortly.
Workarounds
WinRE serves as a vital recovery tool, stepping in when Windows fails to boot properly. It can automatically initiate repairs or allow users to manually select options like a recovery drive or Safe Mode. However, the current glitch complicates this process, as USB peripherals are unusable. Fortunately, there is a workaround available. If users have access to an older PS/2 keyboard or mouse and a compatible port on their PC, they can navigate the WinRE screens without issue. For those unable to utilize this workaround, patience may be required until Microsoft releases its fix. Alternatively, if users can still boot into Windows, they can opt to uninstall the October update by navigating to Windows Update, selecting Update History, and removing the KB5066835 update.
Other Bugs
In addition to the WinRE issue, several other bugs have emerged from the October update. One notable problem affects IIS websites hosted on local machines, causing them to fail to load. This issue, like the WinRE glitch, impacts Windows 11 versions 25H2 and 24H2, along with Windows Server 2025. Microsoft has acknowledged this concern and is working on a fix for a future update.
Another reported issue involves the File Explorer preview window, which may malfunction when attempting to display files downloaded from the cloud or internal networks. Users may encounter error messages suggesting that the file could harm their computer. Although Microsoft has yet to officially recognize this problem, it is hoped that a solution will be forthcoming.
As users navigate these challenges, the tech community remains vigilant, anticipating timely resolutions from Microsoft to restore seamless functionality across its platforms.
