Microsoft has swiftly issued an urgent out-of-band (OOB) update, identified as KB5070773, to rectify a critical glitch in Windows 11. This bug had rendered USB input devices, such as mice and keyboards, non-functional within the Windows Recovery Environment (WinRE). The problem emerged following the deployment of the KB5066835 security update earlier this month, impacting systems operating on Windows 11 versions 24H2, 25H2, and Windows Server 2025. The tech giant has moved quickly to ensure users can regain full control of their devices in recovery scenarios.
