Microsoft has swiftly released an urgent out-of-band (OOB) update, identified as KB5070773, to tackle a pesky bug in Windows 11 that had been causing USB input devices, including mice and keyboards, to stop working within the Windows Recovery Environment (WinRE). This problem emerged following the KB5066835 security update earlier this month, impacting systems operating on Windows 11 versions 24H2, 25H2, and Windows Server 2025. The prompt action by Microsoft aims to ensure users can continue to navigate and troubleshoot their systems without interruption.
