Microsoft recently released an urgent out-of-band (OOB) update, identified as KB5070773, to tackle a pesky 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 impacted devices operating on Windows 11 versions 24H2, 25H2, and Windows Server 2025. The company swiftly moved to address this issue, ensuring users could rely on their USB peripherals once again.
