Microsoft has swiftly released an urgent out-of-band (OOB) update, designated KB5070773, to tackle a problematic bug in Windows 11. This glitch had rendered USB input devices, such as mice and keyboards, non-functional within the Windows Recovery Environment (WinRE). The trouble began following the deployment of the KB5066835 security update earlier this month, impacting machines operating on Windows 11 versions 24H2, 25H2, as well as Windows Server 2025. In response to user concerns, Microsoft has acted promptly to ensure system recovery tools remain accessible and efficient, underscoring their commitment to maintaining seamless user experiences.
