Microsoft recently released an urgent out-of-band (OOB) update, designated as KB5070773, to tackle a troubling bug in Windows 11. This glitch was causing USB input devices, such as keyboards and mice, to become non-functional within the Windows Recovery Environment (WinRE). The problem emerged following the deployment of the KB5066835 security update earlier this month. It primarily impacted systems operating on Windows 11 versions 24H2, 25H2, and Windows Server 2025. This swift response by Microsoft highlights their commitment to ensuring seamless user experiences and maintaining system integrity.
