Microsoft has swiftly released an urgent out-of-band update, labeled KB5070773, to tackle a pesky bug in Windows 11. This glitch was causing USB input devices, such as mice and keyboards, to become non-functional when users accessed the Windows Recovery Environment (WinRE). The problem emerged following the deployment of the KB5066835 security update earlier this month. Systems running Windows 11 versions 24H2, 25H2, as well as Windows Server 2025, were impacted by this issue. In response, Microsoft has acted quickly to ensure that users can continue to navigate their systems without interruption.
