How To Change the Windows XP Product Key

Your Windows XP is not activated. This means you must find your original Windows XP disc, and the sleeve that the disc comes in should have the product key on the back.
Type in this product key to activate Windows.
Thanks for using FixYa.

Use a product key recovery program to find your lost key. An example of such a program is Product Key Explorer

2

Install the program by double-clicking on the file you just downloaded and going through the installation process.

3

Open the program when ready and then click "select computer" and make sure it says "Local Computer." Click on the "Find Keys" button.

4

Locate the program that you installed through your CD-ROM. Next to the product name should be your product key.

Good luck.

If your computer came with it loaded on it, there should be a small sticker somewhere on the computer with the key.

If you purchased it after you purchased the computer the key should be in the documentation that came with the CD.

Sorry, that means you have an illegal key. Whoever gave it to you is a crook.

Did this come on a WinXP disc, or did Windows come preinstalled on the computer? If you lost the CD Key, you're going to have to call Microsoft tech support to get a key to activate it.
