Microsoft Expands Advisory on Windows Shutdown Bug, Pledges Fix in Future Update

Devices using boot hardening features remain affected despite January’s emergency patch.

Overview

  • Microsoft now says the shutdown and hibernation failure also impacts Windows 10 22H2 and Enterprise LTSC 2019/2021, in addition to Windows 11 23H2.
  • The regression occurs on Secure Launch–capable PCs with Virtual Secure Mode enabled, where shutdown or hibernate triggers an unexpected restart.
  • The issue is linked to January updates including KB5073455 on Windows 11 and KB5078131/KB5073724 on Windows 10, per Microsoft’s release health notes.
  • An out‑of‑band update released on January 19 did not fully resolve the problem for all affected devices, and Microsoft now plans a fix in a future Windows update.
  • Until a permanent solution arrives, Microsoft advises using the command "shutdown /s /t 0" as a manual workaround, a step leaving IT teams balancing security updates against operational disruptions.
