- In the work area, locate "DisableTaskMgr". If this value is not there, you will need to create a new DWORD value called DisableTaskMgr. Double click on it. A window will pop up.
- Enter its value data as 0 and press OK.
- Close Registry Editor.
- If Task Manager is still disabled, restart your PC.
