Microsoft has released an emergency update to resolve two serious flaws introduced by the January 2026 security update in Windows 11. The main issue affected the shutdown process on several computers, causing the machines to restart instead of completely shutting down or going into hibernation mode. Essa fix arrived quickly, just days after initial user reports.
The flaw was linked to the Secure Launch feature, a protection technology enabled in many modern devices. Ela prevented the system from closing correctly in specific versions of Windows 11. The company confirmed the problem and acted to minimize the inconveniences.
Another bug fixed involved remote access blocking logins to connecting applications on both Windows 10 and 11. The automatically distributed out-of-band update directly addresses these issues.
- Affected users reported repeated restarts when trying to shut down their PC.
- The Secure Launch interfered with the normal closure flow.
- Remote desktop applications failed to prompt for credentials.
