On March 3, 2026, Microsoft re-released update KB5075039 to restore functionality to the Windows Recovery Environment (WinRE) for Windows 10, which officially fell out of support in October 2025. This update followed a bug caused by dynamic security update KB5067039, released in October 2025, which introduced a problematic USBHUB3.SYS driver version that disabled USB keyboards and mice in WinRE. Microsoft acknowledged this issue on October 17, 2025. In mid-January 2026, Microsoft released recovery updates for Windows 10 and Windows 11, including KB5075039 on January 15, 2026, targeting Windows 10 versions 21H2 and 22H2, but it did not resolve the issue. The re-release of update KB5073933 on March 3, 2026, addressed a critical bug preventing WinRE from starting when the previous update KB5068164 was installed. The installation of KB5073933 is recommended for Windows 10 22H2 users with ESU support to ensure a functional recovery environment.
