Microsoft has swiftly released an urgent out-of-band (OOB) update, identified as KB5070773, to tackle a critical issue in Windows 11 that rendered USB input devices such as mice and keyboards inoperative within the Windows Recovery Environment (WinRE). This problem emerged following the deployment of the KB5066835 security update earlier this month, impacting devices operating on Windows 11 versions 24H2, 25H2, as well as Windows Server 2025. This unexpected glitch prompted Microsoft to act quickly, ensuring that users can once again rely on their USB peripherals during system recovery processes.
