How to Change the Product Key Number in Windows 7

This article will show you how to change the product key number in Windows 7 so that you can use another product key number to activate your Windows 7.

This can be helpful if you have entered the incorrect or no product key number during installation, or you just wanted to use a different product key .

This process may or may not work on Windows Xp.

You can only use a product key for the same Windows 7 edition that you currently have installed. For example, you cannot change the product key in Windows 7 Home Premium with a Windows 7 Ultimate product key.
