A January 2026 Windows 11 update breaks shutdown and hibernation, mainly affecting Enterprise and IoT editions, with no fix yet.

A January 2026 Windows 11 23H2 update has caused shutdown and hibernation failures on some devices, leaving systems running despite user attempts to power off. Microsoft confirms the issue stems from the Secure Launch security feature, affecting Windows 11 Enterprise and IoT editions most, with hibernation completely non-functional. A command prompt workaround exists for forced shutdowns, but no fix is available yet. Additional issues include Outlook POP account freezes and connectivity problems with Azure Virtual Desktop and Windows 365, prompting Microsoft to recommend alternative access methods. The company says a future update will resolve the problems.
