Also when you try to run it by typing "taskmgr" in RUN dialog box, Windows shows following error message:

There might be 2 possible reasons behind this problem:

  • Your system administrator applied the restriction using Registry Editor or Group Policy Editor.
  • Your system has been infected with virus and it has disabled the Task Manager.

If you are already the Administrator of the system, then your system is most probably infected. You should follow the instructions given in following topic first:

Is Your System Infected with a Virus / Spyware / Adware / Trojan?

Now if your system in not infected or you have successfully removed the virus, then you can follow these simple steps to enable Task Manager again:

1. Type regedit in RUN dialog box or Start Menu Search box and press Enter. It'll open Registry Editor. If Registry editor is also disabled, then follow instructions given in following tutorial:

2. Now go to following keys one by one:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Policies\System
HKEY_USERS\.default\Software\Microsoft\Windows\CurrentVersion\Policies\System

and look for a DWORD value "DisableTaskMgr" in right-side pane. If you find it, delete it.
