November 25, 2008

Have you ever run into a situation where you get an alert message that says "Task Manager bad been disabled by your administrator"?

You may encounter this if you are not logged in as the administrator on a particular PC running Windows. Many times you may feel that it is necessary to access the task manager for various reasons. It may be bad news to you if you run into this situation when you must check your system resources or end the task of a running program or file. The good news is you can enable the task manager.

Editing or modifying your system registry may render your system unstable or damaged. Make sure you are able to backup the registry and that you are certain that you follow each step in it’s entirety.

Below is a method demonstrating how to enable a disabled task manager using the Registry Editor and via the Run Menu.

  1. Go to Start menu > Run > type in regedit and then press enter.
  2. Navigate to and find the following registry path: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System
  3. Find the entry DisableTaskMgr. If this entry is not present then you must add one by right clicking the right side pane and then selecting new DWORD value. Rename it DisableTaskMgr. Double click this entry and make sure the DWORD value is set to 00000000.
