Microsoft recently released an urgent out-of-band (OOB) update, identified as KB5070773, to tackle a critical issue impacting Windows 11. This bug, which emerged following the deployment of the KB5066835 security update earlier this month, rendered USB input devices such as mice and keyboards inoperative within the Windows Recovery Environment (WinRE). The problem has been particularly problematic for users operating Windows 11 versions 24H2, 25H2, and Windows Server 2025. This swift intervention by Microsoft aims to restore functionality and ensure a seamless user experience across affected systems.
