Task Manager has been disabled by your administrator

Muhammad Rizwan asks that whenever he tries to open the task manager, he is encountered by the following error:

“Task Manager has been disabled by your administrator”

Here is solution from the Microsoft article about enabling the task manager:

Enabling Task Manager from Group Policy Editor

Warning: Modifying your registry can cause serious problems that may require you to reinstall your operating system.
Always backup your files before doing this registry hack.

2. Navigate to the following registry keys and verity that following settings set to default:
Windows Registry Editor Version 5.00
[HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionPoliciesSystem]
“DisableTaskMgr”=dword:00000000
[HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionGroup Policy ObjectsLocalUserSoftwareMicrosoftWindowsCurrentVersionPoliciesSystem]

3. Reboot the computer.

For your convenience, I have created a registry file. Just download, double click it and add the info to your registry. The task manager will be enabled. Post your experiences please.
