Registry Tools - Version 2.01a Registry Tools is a very easy-to-use utility designed to backup (and if necessary, restore) the Windows Registry. This program has the ability to backup or restore from Windows, Safe Mode, or DOS, and users have the option of making a "fix-it disk" that they can use to restore their Registry settings in the event that Windows becomes corrupted. The cost of registering this shareware is $5.00 and includes a free copy of the next full release version.
