Microsoft Releases Fix for Critical WinRE Bug
Microsoft has acted quickly to address a serious bug. The company released a new software update for Windows 11 users. This fix targets both the 24H2 and 25H2 versions of the operating system. The issue relates to the Windows Recovery Environment (WinRE). This is a vital tool for system recovery.
The problem specifically affects USB devices. After installing Windows updates released on October 14, 2025, users experienced an issue. Their USB mouse and keyboard stopped working inside the WinRE environment. This effectively locked users out of essential recovery tools. This is a critical problem for anyone needing to troubleshoot their system. The affected OS Build is 26100.6899. The patch is available under KB5066835.
The Windows Recovery Environment is crucial for managing system failures. It allows users to perform various tasks. These include system restoration and advanced troubleshooting. A non-functional mouse and keyboard within this environment means users cannot select options. They cannot enter commands. Therefore, any device facing severe boot issues cannot be easily repaired. This bug significantly reduces the reliability of the Windows operating system’s built-in safety nets.
This problem only impacts USB devices. It only appears within WinRE after installing the problematic cumulative update. However, the inability to control the interface in a crisis situation is unacceptable for many users. Consequently, Microsoft prioritized releasing an immediate resolution.
Microsoft has outlined simple steps to apply the resolution. Users in Southeast Asia should follow this process.
- Open Windows Update: Go to the “Windows Update” section within the “Windows Settings” app. Users can quickly access this by searching for “check for updates” in the Start Menu.
- Check for Updates: Click on “Check for updates.” Allow the system to find and install any available updates.
- Restart Device: Regardless of whether new updates were installed in the previous step, restart your device.
Microsoft confirms that the company is actively working on a final, permanent fix. This future update will be fully integrated into the system. The current steps provide an immediate workaround. They restore full functionality to USB devices within WinRE. Users must restart their devices after applying this temporary fix. This ensures the resolution takes effect. The community appreciates this quick response from Microsoft.
