please help !!! i cannot access my windows 10 setting, any system apps, file explorer, no run command , even i can't change the volume.. it says you do not have permission to acces this only third party software is working
i am installing a software then a error appeared while installing it said error creating registry key HKEY_CLASSES_ROOT\.CERTRAINER then i searched for a solution ::: i followed his solution

Try the Repair Permissions tool in Dial-a-fix. This problem is usually caused by malware targeting the application, but Norton Antivirus has been known to cause it by breaking the permissions of HKEY_CLASSES_ROOT, as well.

You can also go to:
Start--> Run--> Regedit

Right click on HKEY_CLASSES_ROOT
Then click on Permissions
Confirm Full Control is ticked

By the way, do not edit/change anything else in registry, other than the above.

From then i am not able to access my PC ?
