Many a times computer users face this problem…
When you try to run Task Manager, you receive the message that 'Task Manager has been disabled by the Administrator'. And the error message seems funny !
You logged in using the Administrator account and still this error message. Strange you don't know how this has happened. The strange thing is that it is on the Administrator user identity that you get this problem.
This all happens due to some malware or spyware software putting some registry restrictions so that one can't trace or remove them from the system startup.
