I still remember some time ago a friend of mine asked why the Task Manager in Windows XP it can not be opened and displays a messagebox with the words "Task Manager has been disabled by your administrator". Then I answer, the computer has been infected with the virus that causes its Task Manager can not be opened.


He was asking how to re-activate the Task His manager, and I give two solutions to enable the Task Manager by manually or by using the registry file that can be directly used. Before you follow the manual way that I give, I menyarakan to scan the computer in advance by using AntiVirus has the latest updates. This can prevent the virus to disable Task Manager back. If the virus has netted only then run the following solution.

While for Windows other than Windows XP Professional to enable following the Task Manager via RegEdit:
