Summary

  • Windows 11’s October update (KB5066835) disrupts USB keyboard and mouse functionality in WinRE, hindering recovery efforts.
  • While USB devices remain operational within the main Windows environment, the recovery options become inaccessible post-update.
  • Microsoft has yet to offer a workaround but assures users that a fix is on the horizon.

In the ever-evolving landscape of technology, the importance of a reliable backup plan cannot be overstated. A common adage reminds us that the safety net designed to catch us in times of crisis must be dependable. Unfortunately, recent experiences have shown that even the most well-laid plans can falter. For users who have recently installed the October update for Windows 11, caution is advised—especially when it comes to the Windows Recovery Environment (WinRE).

The Windows 11 October Update Breaks USB Keyboard and Mouse Input in the Recovery Environment

As highlighted by Tom’s Hardware, Microsoft has updated its documentation regarding the Windows 11 25H2 update, but not in a manner that inspires confidence. A new entry under the “Known issues” section reveals a significant flaw: USB keyboards and mice cease to function within the Windows Recovery Environment following the installation of the security update released on October 14, 2025 (KB5066835).

After installing the Windows security update released on October 14, 2025 (KB5066835), USB devices, such as keyboards and mice, do not function in the Windows Recovery Environment (WinRE). This issue prevents navigation of any of the recovery options within WinRE. Note that the USB keyboard and mouse continue to work normally within the Windows operating system.

This unfortunate development means that if users find themselves in the WinRE, hoping to resolve issues with their Windows 11 system, they will be met with an inability to navigate or select options. The irony is palpable; a tool designed for recovery becomes utterly useless when it is most needed. Currently, Microsoft has not provided any alternative solutions or workarounds, leaving users in a precarious position until a fix is deployed in the coming days.

In the meantime, users are encouraged to explore other methods for troubleshooting Windows 11 issues, albeit without relying on the Recovery Environment. As the situation unfolds, vigilance and patience will be key for those navigating the complexities of this latest update.
