Windows 11 black screen after login

Hi, I work for an IT company and lately we've been having this issue spread around a couple of our clients.

Windows will boot to the login screen fine, but once they log in they'll get stuck on a black screen. Hard rebooting the PC will allow them to login, but this is obviously not efficient or ideal. I've been researching online and found many posts saying that disabling the app readiness service will fix this issue, but that it also prevents you from running Windows Update and may break certain applications.

Besides the temporary solution of disabling app readiness, is there any way to resolve this? Or did Windows push an update that broke something, and we'll have to wait it out.

So far, we've tried:

  • disabling fast startup
  • clearing temp files
  • Setting pc to not sleep
  • uninstalling and reinstalling the graphics driver
  • updating bios

It's occurring on multiple different PCs, so we know it's not hardware related, Windows 11 is the only connecting pattern between them.

    Dear Team,

    Yes, this is a known issue with recent Windows 11 updates (mid-2025) causing black screen after login — often tied to the App Readiness service, user profile loading, or explorer.exe failing to launch.

    Permanent Fixes (without disabling App Readiness):

    Force-start explorer.exe on login

    Press Ctrl + Shift + Esc → Task Manager

      If it's black, use `Ctrl + Alt + Del` → Task Manager
      
         File → Run new task → type `explorer.exe` → Check "Create this task with admin privileges"
         
    
    1. Registry Fix
      1. HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon
      Make sure these values exist and are correct:
      • Shellexplorer.exe
      • UserinitC:\Windows\system32\userinit.exe,
      Check Group Policies If you manage via Active Directory, make sure no login scripts or group policies are delaying profile/app loading. Create a New Local User Profile Corrupted user profiles also trigger black screens. Try creating a new test local admin account and see if it boots normally. Use a Clean Boot for Troubleshooting Disable all non-Microsoft services (via msconfig) and startup apps to isolate third-party conflicts. Patch Rollback (if update caused it) Go to Settings > Windows Update > Update history > Uninstall updates
        Roll back recent **KBs from July 2025**.
