Microsoft has released an out-of-band (OOB) update to patch an issue related to Windows 11's Recovery Environment. Users had reported a major bug that was introduced in this month's Patch Tuesday update.

KB5066835, which was released on October 14, 2025, had a couple of known issues, one of which was related to USB devices not working in the Windows Recovery Environment (WinRE).
