How Task Manager is disabled

Q: Task Manager has been accidentally disabled! Press Ctrl+alt+del to indicate that task Manager has been deactivated by the system administrator. Right-click on the Taskbar pop-up menu, Task Manager is not clickable. How can I remove it?

A: I do not know what operating system is used, if it is not a family version, you can use Group Policy to remove restrictions under the Administrator account: click "Start" → "Run" enter "Gpedit.msc" to open Group Policy Editor, expand: local computer → policy → user configuration → admin template → system →ctrl+ Alt+del option, open the Delete Task Manager property in the list, and select the disabled or Not configured single option from the Settings tab in the Delete Task Manager property to determine.

If it is a home version of Windows, because there is no Group Policy, use the registry to fix it, and navigate to: hkey_current_user//software/microsoft/windows/currentversion/policies/, You do not need this step to establish an item named system under this registry key, such as a system item already under the Policies branch. Then create a "string value" or "DWORD value" named DisableTaskMgr under System key to 0
