From the recovery environment or from another machine with "reg load".
Even safe mode with command prompt?
By the way, there could be an easier way.
From safe mode with command prompt or from the recovery environment, you can navigate to C:\Windows\System32\config and check the sizes of their backups in the regback folder:

If the backups dates are older (than the current corrupted ones) and their sizes are greater than 0 (zero,nought), you can replace the corrupted ones with these backups.
You can also create a backup of the current corrupted files (before the replacement, obviously).
There's a tutorial, if you prefer: Manually Restore the Registry From its Backup in Windows (Windows 7 / Vista)
