After installing the Windows security update released on October 14, 2025 (KB5066835), USB devices, such as keyboards and mice, do not function in the Windows Recovery Environment (WinRE). This issue prevents navigation of any of the recovery options within WinRE. Note that the USB keyboard and mouse continue to work normally within the Windows operating system.

 

Next steps: Microsoft is working to release a solution to resolve this issue in the coming days. More information will be provided when it is available.
