The Magical Jelly Bean Keyfinder is a freeware utility that retrieves your
Product Key (cd key) used to install windows from your registry. It has the
options to copy the key to clipboard, save it to a text file, or print it
for safekeeping. It works on Windows 95, 98, ME, NT4, 2000, XP, Server 2003,
Windows Vista, Office 97, Office XP, and Office 2003.
This version is a quick bug fix to remedy the broken "Change Windows Key" in
Windows XP.
