Install Windows Vista without the product key

Windows Vista has a nice "feature" you may want to know: you can install Windows Vista without having to enter the product key during the setup process. I think the reason for this is to let you test the different versions of Vista before deciding which one to buy. So, when you reach the dialog that asks you to provide a valid product key during setup you can leave it blank! Just click "Next" and answer "No" in the "Are you sure?" dialog box.


The big surprise is that you will be presented with all versions available on the DVD and you can choose one of all the different Windows Vista versions available on the DVD because the product key is the only thing that tells the setup process what version of Vista it should install.


After 14 days you will need to enter a valid product key or do a fresh install.
