You activate by entering the product key for your copy of Vista. You do not
enter an activation code. If Vista came preinstalled on your computer the
product key is on a sticker on your computer (side of the case on desktops
and on the bottom of laptops). If you purchased a retail copy of Vista then
the product key is on the back of the dvd tray in your retail box.
