Re: Windows activation after Sysprep
I hate OEM...
Get a volume license for win 7. Regardless of whether or not you get the SP1 key, you can download SP1 while windows is not activated and then activate after you have SP1. If you get a volume license you can technically activate windows on 3 different machines (only one at a time of course). Before you go purchase another copy though, put the new motherboard and CPU in and phone Microsoft. It's not completely unheard of that they will give you an activation code for your new motherboard and chip.
Edit: a motherboard and CPU count as one point each towards a new system and you need three pnts against you to make the copy invalid. However a NIC counts as three points on its own so since it's integrated, your board may count as four by itself but I'm not completely certain on that. Still give them a call after your upgrade and se what they say.
Humans are the only creatures that won't live up to the their potential. Give everything your all. When you die, die on E.
So I ask you, what do you intend to do now?
