Microsoft has recognized that an increased number of computers with Windows 11 are experiencing shutdown failures after recent updates. The issue causes devices to restart automatically instead of completely shutting down or going to sleep.
The company identified the cause in security features enabled in specific configurations. The flaw mainly affects systems that use Secure Launch, a technology linked to secure boot mode.

The company has expanded the list of impacted devices in recent weeks. Modelos businesses and some consumers with advanced security configurations were included in the affected list.
Most vulnerable configurations
Systems with Secure Launch enabled face the greatest risk. Esse feature protects boot against firmware threats and remains active on Enterprise and Education editions of Windows 11.
Devices that use TPM 2.0 and Secure Boot may also exhibit unexpected behavior. Microsoft confirmed that the problem does not affect all installations, but is growing in recent reports.
Virtual machines and corporate environments register a higher incidence. Usuários households with default settings report isolated cases.
Symptoms observed by users

Microsoft advises avoiding repeated forced shutdown. Essa practice may cause data loss or additional system instability.
History of problematic updates
Windows 11 recorded similar failures in previous updates. Problemas security feature compatibility appeared in versions 22H2 and 23H2.

Next steps for Microsoft
The company is working on a permanent patch for the next update cycle. The full repair should arrive in February 2026 via regular Patch Tuesday.
Internal tests validate the solution on different hardware. Microsoft collaborates with manufacturers to ensure broad compatibility.
Users can monitor the release health dashboard. The official website publishes detailed status of known issues.
The shutdown problem on Windows 11 has gained greater proportions in recent weeks. Microsoft maintains active monitoring and provides support channels for persistent cases.
