Task manager is disabled by your administrator

Let’s face it. All of us have been infected by virus before. Even if you have anti-virus installed, you can still be infected by a new or custom virus that is not recognized by your anti-virus. Sometimes after removing the virus completely from our system, you’ll face new problems such as you can no longer bring up Windows Task Manager from CTRL+ALT+DEL. You get the error message saying “Task Manager has been disabled by your administrator”. This post will help you to re-enable the Windows Task Manager as long as it cannot open normally. Just follow these steps.

Disabling Task Manager is one way viruses try to make it harder for you to deal with their infections. Before proceeding any further, you should run a complete and up-to-date anti-virus scan of your machine. It’s possible, perhaps even likely, that you’ve been infected.Once you come back virus-free, you can proceed with the fix. Usually when you try to run taskmgr.exe manually, you get this message:

METHOD 1:

Open Run, type gpedit.msc

Locate:

 User Configuration\Administrative templates\System\Ctrl+Alt+Del Options

Double click “Remove task manager” and set it as Disabled.
