Windows update leaves some virtual desktops staring into the void
Microsoft has acknowledged a bug in recent Windows 11 updates that causes virtual desktops to fail loading, resulting in a black screen for affected users. The issue primarily impacts Azure Virtual Desktop hosts using FSLogix, requiring users to manually restart Windows Explorer to recover their session. Administrators can deploy a Known Issue Rollback via Group Policy as a temporary measure while Microsoft works on a permanent fix.
- ▪The glitch affects Windows 11 versions 26H1, 25H2, and 24H2 following the August 2026 non-security preview update.
- ▪Users can temporarily resolve the black screen issue by opening Task Manager and running explorer.exe as a new task.
- ▪Microsoft has issued a Known Issue Rollback (KIR) that administrators can deploy through Group Policy to disable the offending change.
- ▪The problem is distinct from a previous issue where customized desktop backgrounds were replaced with solid black, which was fixed in September.
- ▪Microsoft stated the issue appears more frequently with some existing user profiles but has not explained the precise cause.
