A black screen after logging in to Windows 11 usually means the desktop environment (explorer.exe) failed to start, or your display driver stalled. It looks alarming but is almost always fixable without reinstalling Windows.

First: Wait a Minute

Sometimes, especially after a Windows Update, the desktop just takes longer than usual to appear. Give it up to two minutes before assuming something is wrong.

Restart Explorer from Task Manager

If you see your mouse cursor but nothing else, the desktop shell probably crashed.

  1. Press Ctrl + Alt + Delete and click Task Manager.
  2. Click More details if Task Manager opens in compact view.
  3. Go to File > Run new task.
  4. Type explorer.exe and press Enter.

Your desktop and taskbar should reappear immediately.

Fix a Stuck Display Driver

If restarting Explorer doesn't help, the GPU driver may have crashed. Try pressing Win + Ctrl + Shift + B — this resets the graphics driver without rebooting. Your screen will flicker briefly and then recover.

Boot into Safe Mode to Troubleshoot

If the black screen appears every time you log in:

  1. Hold Shift and click the power icon on the login screen, then choose Restart.
  2. Select Troubleshoot > Advanced options > Startup Settings > Restart.
  3. Press 4 to start in Safe Mode.

Once in Safe Mode, uninstall any recently installed apps or drivers. Go to Device Manager, expand Display adapters, right-click your GPU, and choose Update driver or Roll back driver.

Check the Shell Registry Value

Malware sometimes changes the Windows shell registry value, causing a black screen.

  1. In Task Manager, open a new task and type regedit.
  2. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon.
  3. Make sure the value of Shell is exactly explorer.exe. If it says anything else, double-click it and correct it.

Run a System File Check

Open a new task in Task Manager, type cmd, tick Create this task with administrative privileges, and run sfc /scannow. Restart when it finishes.
