Find Product Key for Windows XP, 98, 95, ME, NT4, 2000, Server 2003, Vista

A very simple and straight-forward way to find and change Windows product key is offered by Magical Jelly Bean Keyfinder freeware. In fact, this program can do more. The complete list of what it allows you to do is as following:

• get lost product key for Windows and change it if you need so
• change Windows registration information without having to crawl registry
• - find remote Windows key
• find lost Microsoft Office 97, Office XP, and Office 2003 installation key

This is a stand-alone program so there is no installation required.

Now, you may question its legality as why would anyone change the product key unless what you have is an illegal copy?
As stated on the developer's FAQ page, this is a legal thing to do since Microsot itself provides information of how to change the key together with providing the script specifically made for the replacement process. This program integrates the script into a concise and easy way to executing the process.
