Black screen after logging-in to Windows 10

This is just a memo on the quickest solution for above mentioned problem, in scenario, when you can run Task Manager (Ctrl+Alt+Delete on your keyboard + click Task Manager + click More details).

  1. Validate your shell:
    • in Task Manager: click File > Run new task + type regedit.exe + hit Enter,
    • paste HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon + hit Enter,
    • check Shell key, if it has explorer.exe value; “reset” it to this value otherwise.
  2. Restart shell: in Task Manager: locate File Explorer (explorer.exe) right-click it + select Restart.
  3. Restart computer: in Task Manager: click File > Run new task + type shutdown /s -t 01 + hit Enter.

Each run in Task Manager must be with Create this task with administrative privileges checked.

It is important to restart computer exactly this way (with executing these parameters), as described above. In my case this was an essential point into solving this issue, as shell was OK and restarting it didn’t help.

If this solution doesn’t work (shell is not restarted or no positive effect after restarting whole computer) then you must ask uncle Google for more help, because this quick memo won’t help you, sorry.
