Microsoft's initial Windows 11 security update for 2026, released on January 13th, quickly led to significant problems, forcing the company to issue an emergency out-of-band update just four days later. The problematic patch caused some computers to fail to shut down or hibernate correctly, and also disrupted remote desktop login capabilities for certain users.
The most notable bug prevented some systems running Windows 11 version 23H2, specifically the Enterprise and IoT editions, from shutting down or hibernating as expected. This issue was linked to devices utilizing Secure Launch.
In addition to the shutdown bug, the update also caused connection and authentication failures in remote connection applications. This problem impacted a broader range of systems, including Windows 11 version 25H2, Windows 10 version 22H2 ESU, and Windows Server 2025.
Recognizing the severity of these issues, Microsoft swiftly deployed an out-of-band (OOB) update on January 17, 2026. This emergency patch aimed to resolve both the shutdown/hibernation failures and the remote connection problems, restoring normal functionality for affected users. This incident highlights a growing trend of buggy updates requiring rapid out-of-band fixes from Microsoft.
