Used This One For Years - Reg Backup/Restore -Win NT - 7

ERUNT  ERUNT Portable
System Req: Win NT - 7

Description:
An exceptional registry backup/restore program that's small and very
efficient.
The standard registry backup options that come with Windows, back up
most of the registry, but not all of it. If you scour the internet to
do some research on this must have program, you will find a lot of
satisfied users. Once you have this program, theres no more need for
you to use the system retore function. Here's one happy user's
comment. "I've used ERUNT for years, and restored with it many times,
and it hasn't let me down yet". It comes with an autoback feature that
backs up your entire registry every time you logon into Windows. Also
if you look into the readme file you can use command line switches to
customize to your needs. I would highly recommend you get this. You
never can be too careful.
