Windows Registry Editor Version 5.00 [HKEY_CURRENT_USER\Software\Microsoft\Windows\Curre ntVersion\Policies\System] “DisableTaskMgr” =dword:00000000
Save the file as Enable Task Manager.reg or *.reg.
Open the file by double clicking on it.
Registry Editor will ask you for confirmation. In the confirmation Window, click Yes.
