Microsoft's KB5070773 out-of-band update restores Windows Recovery Environment (WinRE) usability after the October 2025 security updates broke USB mouse and keyboard navigation. The regression affected Windows 11 24H2, Windows 11 25H2, and Windows Server 2025, and it blocked users from selecting recovery options inside WinRE. Microsoft told customers to install the latest update, and it documented recovery paths such as touch keyboards, PS/2 input, USB recovery drives, and PXE/WinPE deployment for systems that cannot boot.
