You have now created a backup of the registry.

Restore:

1.) Go into the run menu again and type cmd.
2.) Type in the 2 commands that was shown in the backup section except in each command swap the twon directores.
(e.g.) "copy c:\windows\system.dat c:\windows\system.000" will become "copy c:\windows\system.000 c:\windows\system.dat"

Whatever was backed up when you created the backup file will be restored to the windows registry.
