We normally open Task Manager when we want to end applications, check on processes, monitor performance or carry out such system related tasks. To do so, we either right-click the taskbar and select Task Manager, press Ctrl+Shift+Esc or type taskmgr in start search and hit Enter to open the Task Manager
Task Manager not opening
But it may happen that one fine day you find that your Task Manager will not open. In such a case you will have to find out the reason – whether the Task Manager has been disabled by your Administrator or whether it is due to some other reason.
When you try to open the Task Manager, do you get: Task Manager has been disabled by your Administrator message? If so you can contact your admin with your problem.
But if you are the sole user of the computer and you still get this message, you can try the following suggestions:
First, open regedit and navigate to the following key:
Here if you find a registry key DisableTaskMgr, simply delete the key, or set its value to 0.
Alternatively, you could type gpedit.msc in start search and hit Enter to open Group Policy.
User Configuration > Administrative Templates > System > Ctrl+Alt+Delete Options > Remove Task Manager.
Right click it > Edit > Select Not Configured > Click Apply-OK-Exit.
Restart the computer and see if it helps!
