ENABLE/DISABLE:

The Task Manger can normally be accessed by right clicking the Task Bar and selecting the Task Manager option from the pop up menu. However, for security reasons it makes sense to disable the Task Manager. This can be done easily with the help of a simple Windows Registry trick:


  • Open the Windows Registry (Start -> Run -> Type regedit)
  • Browse the rigistry key below:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System


  • In the right pane creat a new DWORD value called DisableTaskMgr
  • Give it a value of 1 to disable the Task Manger and a value of 0 to enable.
  • Restart the Computer

 ERROR: Task Manager has been disabled by your administrator

 That’s a very common problem for Windows users. Many times when you try to open Task Manager, it shows following error message:

“Task Manager has been disabled by your administrator”.

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.


How to Fix:

  • Open the Windows Registry (Start -> Run -> Type regedit)
  • 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

  • look for a DWORD value "DisableTaskMgr" in right-side pane, delete it.
  • Now Task Manager will be enabled.
