Picked this program up via TUCOWS because I wanted all of my serial numbers before using javacool's IDBlaster. It's freeware as long as you do not use it for anything other than your personal use. It contains no spyware. (I like to share the good things in life.) Compatible with: Win 95/98/98se/NT/2000/ME/XP. Links are also provided in the listing so you can see where they are located on your system.
