Microsoft warns that Windows 11 23H2 Enterprise/IoT systems with System Guard Secure Launch may restart instead of shutting down or hibernating after installing KB5073455; affected users can shut down via the command shutdown /s /t 0 while a permanent fix is pending, with no hibernation workaround available. The update also references an ongoing Remote Desktop connection/authentication issue tied to KB5074109 and notes a separate, recently resolved false positive in security tools flagging a core Windows component.
