I want to delete a setting in the registry using winreg python but I get the following error: WindowsError: [Error 2]

Question

Key_Name = 'SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System'
key = winreg.OpenKey(winreg.HKEY_LOCAL_MACHINE, Key_Name, 0, winreg.KEY_ALL_ACCESS)
winreg.DeleteKey(key, 'DisableTaskMgr')

winreg.CloseKey(key)
