Task Manager has been disabled by your Administrator

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 or a message like Task Manager is not responding, you can try the following suggestions:

First, open regedit and navigate to the following key:

HKEY_CURRENT_USERSoftwareMicrosoftWindows CurrentVersionPoliciesSystem

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!

Other things you could try to fix the issue:

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.
