Microsoft has swiftly released an urgent out-of-band update, identified as KB5070773, to tackle a pesky bug in Windows 11. This glitch was causing USB input devices, such as mice and keyboards, to be unresponsive in the Windows Recovery Environment (WinRE).

It has primarily impacted systems operating on Windows 11 versions 24H2, 25H2, and Windows Server 2025.
In response to user feedback and to prevent further disruption, Microsoft’s quick issuance of this update underscores their commitment to maintaining system functionality and user convenience. This proactive measure aims to restore normalcy and ensure that users can rely on their devices without interruption.
