How can I retrieve my Windows 2000/XP/2003 or Office 2000/XP CD Key?
Sometimes you might need to retrieve the CD Key used to
install Windows in order to find out if it's legally purchased, or just
for safe keeping. I usually find myself in that position whenever I'm at
a client's location, trying to see if the copy of Windows 2000 he's
using is indeed legally registered.
Luckily for us, some programs exist that can help you do just that -
retrieve license information from the registry, and allow you to copy it
for safekeeping or for documentation purposes. Magical Jelly Bean Keyfinder
