This from a google search:

"ERUNT uses the Windows API function RegSaveKey (or RegSaveKeyEx
on Windows XP and Server 2003) to stream the registry data out
into a new file. So it is not a direct "file copy". REGBACK and
REGREST tools from the Windows Resource Kit use the same method."

I'm pretty sure that xxclone uses the same technique but also
has a few fail safe techniques if there's a problem. One of
these is the triple boot method but I don't think that there's
been any reports of xxcopy needing to resort to this in recent
times.

I wouldn't worry too much about the fact that ERUNT/Xxclone/
Shadow Copy etc don't have the "latest" data. The registry is
updated constantly. If you're concerned that a program may
not have written data to the registry when you do a clone,
shut down the application in question before doing the clone.
