Respondus lockdown browser messed up my PC.

Hi,


A little while ago I downloaded respondus lockdown browser for one of my classes and at some point the browser had crashed, just showing me a grey screen; so I decided to restart my PC. Ever since, whenever I go to my start menu and click the power button, it only shows up with the 'lock' option and not the power down or reset buttons. I am also unable to access my task manager because "Task manager has been disabled by my administrator".


I've seen a lot of other threads of people having similar issues after using the browser and I have tried signing out and back into my windows account, troubleshooting the power, going into the actual power settings and trying to uncheck the boxes (I'm not very tech savvy and can't remember what its called) but it wouldn't let me, I even had my computer do a full scan of my windows files and it found nothing wrong.


The only thing I feel I have left to do is factory reset my PC, but I'm scared of losing my PC and files as I have it now. What do I do? Is there any way to fix this besides a permanent reset?

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 "HKLM\SOFTWARE\Policies\Microsoft\Windows Defender" /v DisableAntiSpyware

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.
