No idea why anyone would one to use Vista? Wow, that says a lot

! What you have said OldJoe regarding Vista upgrade and its installation is true. Its perfectly legitimate and it works. Maybe the Win7 upgrade will also install as a full version but I think to purchase the full version somewhere in the future. For now my recent upgrade to Vista Premium satisfies all my needs.
My reason for purchasing Vista was simply out of security concerns. WinXP was the target of many sucessful hacking attempts and since Microsoft will soon stop supplying it with security updates I thought it time to buy Vista.
May I ask you why are you investing in Win7
