A recent bug in Windows 11’s October update (KB5066835) has broken the Windows Recovery Environment (RE), making it unusable for troubleshooting and repairs. The issue affects users who plug in a USB keyboard and mouse, rendering them unresponsive when entering RE mode.
Microsoft has confirmed that a fix is being worked on to address this problem, but in the meantime, affected users can continue to use their peripherals normally within the main operating system. However, those relying on Windows RE for troubleshooting or repairs may need to wait for a solution.
This latest bug follows other recent issues with Windows updates, including an emergency fix for localhost connections and problems affecting IT personnel who rely on Windows RE for sensitive repairs.
Microsoft has acknowledged that proper quality assurance (QA) could have caught this issue earlier. As the company continues to prioritize AI and advertisement features, some users are expressing frustration with what they see as a decrease in overall system stability.
