Microsoft Faces Shutdown and Hibernation Issues Across Windows 10 and 11
2/4/2026, 1:15:26 AM
Overview of the Shutdown and Hibernation Bug
In January 2026, Microsoft released a security update that inadvertently introduced a significant shutdown and hibernation issue affecting multiple versions of Windows, including Windows 10 and Windows 11. Initially reported in Windows 11 version 23H2, the problem has since been confirmed to impact Windows 10 version 22H2, Windows 10 Enterprise LTSC 2021, and Windows 10 Enterprise LTSC 2019. Users attempting to shut down or hibernate their devices experienced unexpected restarts instead.
Technical Background of the Issue
The shutdown problem arose from a conflict between the January security updates and Microsoft's System Guard Secure Launch feature, which is designed to verify firmware integrity during system startup. Following the update, this security mechanism misinterpreted shutdown signals as unauthorized changes, leading to the malfunction. Microsoft has acknowledged that devices with Virtual Secure Mode (VSM) enabled are particularly susceptible to this issue.
Timeline of Microsoft's Response
- January 13, 2026: Microsoft released the KB5073455 security update, which introduced the shutdown and hibernation bug.
- January 17, 2026: Emergency updates KB5077797 and KB5077744 were issued for Windows 11 versions 23H2 and 24H2/25H2, respectively.
- January 19, 2026: An out-of-band update was released, but reports of ongoing issues persisted.
- January 30, 2026: Microsoft confirmed via its Release Health Dashboard that problems remained unresolved, particularly for devices with VSM enabled.
Official Statements & Responses
Microsoft has stated that it plans to address the ongoing issues in a future Windows update. The company noted, "We plan to resolve this issue in a future Windows update," acknowledging that some devices continue to experience problems even after applying the emergency fixes. Windows boss Pavan Davuluri emphasized the company's commitment to improving the operating system's reliability.
Criticism & Opposition
Critics have expressed concern over Microsoft's handling of the situation, particularly the admission that the emergency updates did not fully resolve the issues. Some users have voiced frustration over the lack of a timely and effective solution, highlighting the risks associated with either applying the updates or leaving devices vulnerable without them. The situation has raised questions about the reliability of Microsoft's update processes and the impact on enterprise users who rely on stable operating systems.
Conflicting Reports & Gaps
While Microsoft has confirmed the existence of the shutdown and hibernation issues, there are discrepancies regarding the extent of the impact. Some reports indicate that only specific configurations are affected, while others suggest a broader range of devices is experiencing problems. Additionally, the exact changes that led to the introduction of the bug remain unclear, leaving users uncertain about the root cause.

- “Failing to install this could leave customer devices vulnerable.” — The Register
- “Hopefully, Davuluri's promises won't simply result in yet more Copilot content being shoved into Windows rather than addressing whatever went wrong in Redmond that led to a start to the year as bad as 2026's.” — The Register
As Microsoft continues to navigate this issue, users are advised to monitor updates and consider workarounds, such as using Command Prompt to force shutdowns, while awaiting a permanent resolution.
