How to change your Windows Vista product key

A Windows Vista installation disk essentially has all of the various editions of Vista included on that one disk. Which version gets installed is dependent on what product key you enter during the installation process. At some point you may want to upgrade your current version to a version with more bells and whistles, which would require a new Product Key.

Or you may want to Activate your Windows Vista under a different Product Key for some reason. The easiest way to change your Product Key is through the System applet in the control panel

Under the Windows Activation section there is a link: Change Product Key. Clicking that link brings up the screen shown below where you can enter in a different Product Key

And thats it really but remember you are not able to enter any key only a valid Windows Vista key so dont please make sure you have a valid Windows Vista key
