Question

The power options of shut down, and restart locked.

FRANK ARMENIO 20

The 4 squares icon on my Lenovo PC will not allow me to use the power options of shutdown or restart and is showing a padlock symbol. The only way I can shutdown or start my PC is using the manual power button. How do I fix?

Answer 1

Did you install the LockDown browser on your PC to take an exam online, that is the usual cause of this problem.

Click your Start Button, then just type cmd

On the resulting list, right click Command Prompt and select 'run as Administrator'

Paste each of these commands into Command one at a time and press Enter, wait for each command to complete, before running the next command, if you receive an error on any command, ignore that and continue to the next command.

reg delete "HKLM\Software\Microsoft\Windows\CurrentVersion\Policies" /f

reg delete "HKLM\Software\Microsoft\WindowsSelfHost" /f

reg delete "HKLM\Software\Policies" /f

reg delete "HKLM\Software\WOW6432Node\Microsoft\Policies" /f

reg delete "HKLM\Software\WOW6432Node\Microsoft\Windows\CurrentVersion\Policies" /f

reg delete "HKCU\Software\Microsoft\Windows\CurrentVersion\Policies" /f

reg delete "HKCU\Software\Microsoft\WindowsSelfHost" /f

reg delete "HKCU\Software\Policies" /f

reg delete "HKLM\Software\Microsoft\Policies" /f

Then, close Command Prompt and restart (not shut down) your PC
