Task Manager Has Been Disabled, How to Fix It?

Many times when working on a computer that has been infected with a virus, trojan, or piece of spyware I find myself with the Task Manager being disabled. Malware creators like to disable Task Manager so it makes solving the problem and removing the issue difficult.

If this happens you'll normally have to edit the Windows registry to fix the problem. A restriction has been placed on the user to not allow them to run Task Manager, this might be ok in an office environment where the IT department wants to control things, but in a home office this can cause major problems trying to fix a malware or virus issue.
