Microsoft confirmed a known shutdown bug that affected Windows 11 also impacts Windows 10 systems when Virtual Secure Mode (VSM) is enabled. Affected users can use the command “shutdown /s /t 0” as a temporary workaround while Microsoft prepares a future update to fix VSM-enabled systems. #VirtualSecureMode #SystemGuardSecureLaunch
Keypoints
- The shutdown issue was first reported for Windows 11 23H2 with KB5073455 and System Guard Secure Launch enabled.
- Microsoft later confirmed Windows 10 22H2 and Enterprise LTSC 2021/2019 are also affected when VSM is enabled after KB5078131 and KB5073724.
- Virtual Secure Mode (VSM) creates an isolated secure kernel to protect credentials, encryption keys, and security tokens from kernel-level attacks.
- Microsoft released out-of-band updates for some systems and advises using “shutdown /s /t 0” as a temporary workaround for affected devices.
- A permanent fix for VSM-enabled systems will arrive in a future Windows update, and Microsoft has been addressing other update-related issues concurrently.
