Task Manager not opening or disabled by administrator in Windows

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:

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

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.

Navigate to:

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!

But if still, you find that your Task Manager is not opening or working, try these troubleshooting steps:

1. Malware may prevent opening of Task Manager. So you may want to clear your PC junk files and then run a full or deep scan with your antivirus or security software or Microsoft Security Essentials.

2. Check this post on Folder Options Missing, Task Manager Disabled, Regedit Disabled.

3. Run System File Checker by running sfc /scannow and see if it helps you.

4. Use our free tool FixWin to fix this Task Manager not opening problem and many other Windows problems easily.

5. Try Remove Restrictions Tool or Re-Enable to re-enable your Task Manager.

If all fails, you may have to do a Repair Install. If that is not an option you’d like to consider, you can use Process Explorer from Sysinternals or Customized Task Manager from TechNet to achieve the same purpose.
