Windows 7 from Vista Ultimate (packaged)
My son is building his first machine from scratch. He is going to put Windows 7 (64 bit) on it.
I have an unopened/unactivated Windows Vista Ultimate that I won a few years ago. I am wondering if he can just by a Windows 7 (64) upgrade and upgrade from this copy of Vista w/o actually installing Vista.
thank you for your help.
