Microsoft's October 2025 Windows 11 Update Causes Critical Recovery and Localhost Failures
TL;DR Summary
Microsoft has confirmed that the October 2025 update for Windows 11 (KB5066835) causes a bug that disables mouse and keyboard functionality in the Windows Recovery Environment (WinRE), making it unusable. The issue affects navigation within WinRE, although USB devices still work within the main OS. Microsoft is investigating and plans to release an out-of-band update to fix the problem. As a temporary workaround, users can revert to an older version of the WinRE image or uninstall the problematic update.
