Thanks. Yeah part of me wants to fire one of them up in a VM just to tinker around a bit since I never messed with the betas. And it would seem that I'd be linking a 10 product key to my account, but then again it might just create headaches later when I try to actually use them. It sounds like it's going to suck though, for anyone that doesn't keep their hardware static for any length of time. A PC to me is just a set of evolving parts.
As long as you don't change the motherboard, it won't care. Even then you likely only need to do the automated phone set up to fix that.
