Common Black Screen Scenarios • Black screen after login with only the mouse cursor visible. • No desktop icons or taskbar, even though Task Manager can be opened. • Partial recovery after reboot on some PCs, while others remain black-screened.

Possible Solutions

1. Restart Explorer Process: ○ Press Ctrl + Alt + Delete and open Task Manager. ○ Find Windows Explorer under the Processes tab, right-click and choose Restart.
2. Uninstall Problematic Updates: ○ Go to Settings > Windows Update > Update history > Uninstall updates. ○ Select the most recent patches and uninstall them.
3. Boot into Safe Mode: ○ Restart the PC and repeatedly press F8 (or Shift + F8) to access Advanced Boot Options. ○ Choose Safe Mode, then uninstall updates or roll back drivers.
4. Update or Roll Back Graphics Driver: ○ In Device Manager, locate Display adapters. ○ Right-click your GPU > choose Update driver or Roll back driver if the issue started after an update.
5. Use System Restore: ○ If system restore points were created, roll the system back to a known good state.

Recommendations • Keep drivers, especially display drivers, up to date before applying Windows updates. • Always create a restore point or full backup before applying major updates. • Watch official Microsoft support or forums for any new advisories on patch-related issues.

Please feel free to let me know if you still have any questions.

Best regards,
