Hi Alex - In addition to the approach Dave outlined for you, you can also
use Erunt/Erdnt. The following will also explain a little about why you
CANNOT get a full backup and a correct restore using the Export/Import
functions in Regedit.



Get Erunt here for all NT-based computers including XP:
http://www.larshederer.homepage.t-online.de/erunt/ I've set it up to take a
scheduled backup each night at 12:01AM on a weekly round-robin basis, and a
Monthly on the 1st of each month. See here for how to set that up:
http://www.larshederer.homepage.t-online.de/erunt/erunt.txt, and for some
useful information about this subject

The following tutorials are useful:

To see an illustrated registry restore procedure
http://www.silentrunners.org/sr_erdntuse.html

This program is one of the best things around - saved my *** on many
occasions, and will also run very nicely from a DOS prompt (in case you've
done something that won't let you boot any more and need to revert to a
previous Registry) IF you're FAT32 OR have a DOS startup disk with NTFS
write drivers in an NTFS system. (There is also a way using the Recovery
Console to get back to being "bootable" even without separate DOS write NTFS
drivers, after which you can do a normal ERDNT restore. See erunt.txt for
detailed instructions. Basically, if you make your backup into a folder
inside your Windows or Winnt folder, you can restore at a Recovery Console
boot by copying the files from that ERDNT folder into the system32\config
folder. After a good boot, then do another normal ERDNT restore to also
restore the user hives also.) (BTW, it also includes a Registry defragger
program). Free, and very, very highly recommended.

FYI, quoting from the above document:

Note: The "Export registry" function in Regedit is USELESS (!) to make a
complete backup of the registry. Neither does it export the whole registry
(for example, no information from the "SECURITY" hive is saved), nor can the
exported file be used later to replace the current registry with the old
one. Instead, if you re-import the file, it is merged with the current
registry, leaving you with an absolute mess of old and new registry keys.


Perhaps this will help you a little.
