Actually you'd just need to write a little app that made a call to
RegReplaceKey
(http://msdn.microsoft.com/en-us/library/ms724913%28VS.85%29.aspx).
Interestingly the documentation regarding VSS restore of the registry
says you should use MoveFileEx with a parameter of
MOVEFILE_DELAY_UNTIL_REBOOT to replace the registry hive with the
restored file, but if you do that your system blows up, so don't do that
:)
