Microsoft has officially acknowledged a significant bug affecting USB mice and keyboards in the Windows Recovery Environment (WinRE) following the installation of security update KB5066835, released on October 14. This issue is specifically impacting users of Windows 11 version 25H2 (2025 Update) when they attempt to access WinRE, which is the diagnostic toolset essential for troubleshooting boot failures.
While USB devices function normally within the standard Windows operating environment, the problem arises exclusively in WinRE. Users may access WinRE when Windows fails to start multiple times, or they can manually trigger it by interrupting the boot process twice—by holding the power button before Windows begins to load. Upon the third startup attempt, the system will automatically enter WinRE. This automatic transition is meant to aid users in resolving issues, but the current bug complicates matters significantly.
In response to mounting user frustration, Microsoft has stated that their engineering team is actively working on a fix, which is expected to be released in the coming days. However, this announcement offers little reassurance to those who are currently grappling with the inability to use their USB input devices while trying to diagnose PC problems.
This incident draws parallels to the early days of Windows 95, when initial USB support was hindered by outdated BIOS firmware. Many users found themselves unable to access BIOS settings due to the reliance on USB keyboards, forcing them to seek out legacy PS/2 keyboards as a workaround. Such historical echoes underline the ongoing challenges faced by users in adapting to modern technology.
The community has voiced their concerns, with some users reminiscing about the stability and support of Windows 10. Many are calling for continued support for Windows 10 until 2030, emphasizing the need for reliable updates and a seamless user experience. As Microsoft navigates these ongoing issues, the importance of effective communication and timely fixes has never been more critical.
As the situation develops, users are encouraged to stay informed about updates from Microsoft regarding this bug and potential solutions. The tech giant’s ability to address these issues promptly will play a crucial role in maintaining user trust and satisfaction moving forward.
