In Windows, hit Start and type regedit, then hit enter to launch the Registry Editor. Navigate to ComputerHKEY_LOCAL_MACHINESYSTEMSetupMoSetup, either by pasting that whole address into the box just beneath “File, Edit, View, Favorites, Help” or by drilling down through the HKEY_LOCAL_MACHINE and System and Setup and MoSetup folders one at a time.
