This is a guide by me so all rules are followed.
I made this in 2011 but i never posted it here. I guess it's time to do that. So lets get to it!
Is your task manager or registry editor or even both disabled?
Does your antivirus remove the virus who causes it but it doesn't remove the restriction to the task manager &/or registry editor?
It's easy to enable it back and it often gets disabled because of a virus.
