Will my Windows Vista product key also work w/ Windows 7? -

Nope, the product key is specific to the product you re using it for. an XP code won t work with Vista, and a Vista code won t work with 7.

No. Just use the beta key Microsoft gives you.

no, download the official beta from microsoft and they will give you a key

no, i guess not, even same XP with different SP had different keys,, okay maybe some people might think they r retard but they r not that crazy enough

NO, but when you download windows 7 beta, Microsoft should provided you with a product key.
