Windows 11 devices, especially after the January 2026 security update, have encountered a specific bug: when trying to shut down the computer, it restarts instead of turning off. The issue affects only a small group of users — those with systems that have Secure Launch, a security feature designed to protect the system’s startup process and verify firmware integrity to prevent tampering or hardware-level malware.
Emergency Patch Released to Fix the Shutdown Bug
Fortunately, this malfunction does not affect everyone. Only devices running Windows 11 with Secure Launch enabled have experienced the issue. For these users, attempts to shut down their PC resulted in an automatic reboot, forcing them to use unsafe manual methods to power off their machines.
In addition, the same January update caused problems for users trying to connect remotely to their PCs through remote desktop apps. Many found themselves stuck at the login screen because their credentials were being rejected, making it impossible to access their systems.
To address these problems, Microsoft has released an out-of-band (OOB) emergency patch, now available through the Microsoft Update Catalog. While the main bug has been resolved, some users still report minor issues such as black screens or unexpected app crashes.
According to Microsoft’s official notes, the update fixes:
- Connection and authentication failures in remote connection applications: This issue affects multiple platforms including Windows 11, version 25H2; Windows 10, version 22H2 ESU; and Windows Server 2025.
- Devices with Secure Launch might fail to shut down or hibernate: This issue only affects Windows 11, version 23H2.
Meanwhile, Microsoft has started rolling out the first test builds of Windows 11 version 26H1. These early builds don’t introduce major new features but focus on internal improvements and architectural changes. The goal is to prepare Windows 11 for upcoming processors based on Arm and hybrid architectures, ensuring better compatibility and efficiency for future generations of PCs.
