Task Manager has been disabled by your administrator

Summary: Task manager can be disabled manually, but more commonly it’s disabled by a virus. It’s easy to re-enable once you’re virus-free.

IMPORTANT: If this restriction was enabled in your system without you doing anything or without your knowledge, then it’s highly likely that a Virus has blocked the usage of Task Manager in your system by enabling the DisableTaskMgr policy via the registry. I strongly suggest that you perform a thorough checkup of your system immediately. Steps listed in the Resolution section of this article helps you unblock the Task Manager, but that does not remove the Virus (if any) from your system.

  1. The group policy is as told by yourself.
