Microsoft has released an emergency update to address a bizarre bug affecting some Windows 11 users: computers were repeatedly restarting instead of shutting down or hibernating. The issue surfaced after the installation of January’s security update, according to reports from Engadget.
The company also resolved a separate bug that impacted remote access functionality with the out-of-band release. This comes as Microsoft continues to refine the Windows 11 experience, balancing feature updates with crucial security patches.
Microsoft explained that the shutdown and hibernation problems occurred when the Secure Launch feature was enabled. Secure Launch is a security measure designed to protect computers from firmware-level attacks during the startup process. The update aims to restore normal system behavior for users relying on this security feature.
Users can install the fix through the Windows Update section in the Settings app.
