Windows 11 Update Causes Black Screen and Desktop Loading Issues After Sign-In
Microsoft says Windows 11 preview updates can black-screen Azure Virtual Desktop sessions that use FSLogix.
Microsoft confirmed that Windows 11 devices which installed August 2026 non-security preview updates, and possibly later cumulative updates, can show a black screen after sign-in or fail to load the desktop. Version 26H1 is linked to KB5120996, OS Build 28000.2804, while 24H2 and 25H2 are linked to KB5120998. Azure Virtual Desktop session hosts using FSLogix are most frequently affected, and Application logs may show Explorer.exe crashes. Microsoft is mitigating the issue with Known Issue Rollback policies KB5124006 and KB5124010 and has not yet released a permanent fix.
- Users can sign in and then see a black screen or no desktop.
- Microsoft ties the regression to KB5120996 and KB5120998.
- Azure Virtual Desktop hosts using FSLogix are most often affected.
- Rollback policies KB5124006 and KB5124010 disable the faulty change.
- Relaunching explorer.exe restores the shell but does not fix the bug.
