Reinstalling Microsoft Office XP soon? If you can't find your Microsoft Office XP product key, sometimes called a CD key, you're going to need to extract it from your current installation.
Normally this product key is on a sticker attached to the inside of your CD case or located with the manual that came with Office XP.

Manually locating the Microsoft Office XP product key from the registry is nearly impossible due to the fact that it's encrypted. Luckily, a number of free programs exist to help find product keys.
