If you're preparing to reinstall an operating system (for example, doing a clean install of Windows XP) or another program, you will need to find your copy of the software's product key (CD key) - sometimes also referred to as a serial number.

Normally this product key is located with the original manual or CD. If you've lost your product key you can often find it in the Windows Registry but this can be very difficult to do. Luckily, there are many free key finder programs available to help.
