I have a windows vista home basic on my laptop. I also have a legit license key for windows vista business edition. But not the disc, only the key. So can i upgrade home basic to windows vista business edition just by right clicking on my computer, going to properties, then go to windows activation place. And click on the change product key button. Then just enter the vista business key and click next and see what happens....?

That might work. But since it is for a full version you might have to re-install. That method might only work with the anytime upgrade serials which are different than full retail ones.
