Vista product key after upgrading to windows 8

[Greykeymedia]

Hello,
Well I was thinking, if I upgrade my current dell desktop that shipped with vista to windows 8 after I upgrade will I be able to use my vista product key to activate vista on another machine/ virtual machine? Thank you in advance!

No. That key is tied to the Dell machine. It cannot be used anywhere else.
