How to enable Task Manager in Windows?

Last two weeks, when I pressed Ctrl+Alt+Del to open up the Task Manager, suddenly this error message appeared on the screen,

Task Manager has been disabled by your administrator.

It was weird because I am the administrator of the computer and I didn’t disable it but how come it says the Task Manager has been disabled by me, the admin?

First thing came to my mind was, it most probably the computer has been infected by a virus and the virus has modified the registry keys, disabled the Task Manager.

The Solution?

Here is the quick fix to re-enable the Task Manager using Registry Editor in Windows.


  1. Press “Windows Key” + “R”.
  2. Type “regedit” and press Enter.
  3. Navigate to,

    HKEY_CURRENT_USER\Software\Microsoft\Windows\Current Version\Policies\System

  4. Double click on “Disable TaskMgr” at the right pane.
  5. Set the value to 0.
  6. Restart the computer.

Hope this helps!

    Sometimes though, even regedit itself becomes disabled, and I have to resort to using utilities such as virus effect remover.
    At least your post lets me know what those utilities do to my registry.
