Prevent users from using Windows Task Manager

Windows Task Manager allows users to start and stop programs, view programs running on their computers which include system services, identify executable names of programs, and change the priority of the process in which programs run. In the hands of the wrong users these useful features can do more harm than good.

However, if you want to prevent users from starting Task Manager on their computers you can enable a Group Policy which alerts users that this tool has been disabled.

To set the Remove Task Manager policy on a local computer follow these steps:

  1. Open the Local Group Policy Editor snap-in by typing gpedit.msc in the Start search text box and press enter.
  2. Go to Local Computer Policy\User Configuration\Administrative Templates\System\Ctrl+Alt+Del Options node.
  3. Double click Remove Task Manager from the Settings pane and check the Enabled radio button.
  4. Click Apply and OK.

To disable this setting and allow the use of Task Manager, check the Not Configured option. The same policy can be set in corporate environments using domain-wide Group Policy.
