First of all, I know this question has been asked to death but I've been researching all day and still cannot find a straight answer, I'm fatigued and asked everywhere. I just want to pre order Windows 8 and be done with it I do not have an activated version of Windows 7, and I am currently running an inactivated Windows 8 RTM. I intend to purchase Windows 8 (or pre-purchase) on Friday. I have no idea whether I should buy Windows 8 (upgrade?) or Windows 8 System Builder My BIGGEST concern is whether System Buillder willl be locked to my specific motherboard (the way W7 OEM works) or whether I can transfer my license to a "new" system (if I happen to format, which I do a lot, or upgrade my motherboard) tl;dr: Is the only viable option the "System Builder" copy? Or can I buy the boxed Windows 7 Pro "upgrade" copy? Is the System Builder locked to specific hardware as OEMs are? I'm really disappointed in retailers/Microsoft for the poor description of this product. It's very confusing and not clear.
For ehat I understand : - Retail : No more - Upgrade : REquire to have a previous version installed. Will be bind to that computer only - OEM : Bound to one computer only. Officially, can not be bought by an end-user - PUL : A OEM version sold to end-user. Bound to one computer only also I think taht we won't be able anymore to create migrate Windwos 8 from computer to computer.... be I was not able to find the full EULA text, so I may be wrong... :S
Forget what I said. Here is the text I found Code: In other words, you can remove the Windows 8 upgrade from an original PC and then install it on another PC, assuming the new PC has a license that qualifies it for an upgrade. Likewise, you can completely remove the PUL System Builder software from a self-built PC, a VM, or a partition and then install it in a new physical or virtual PC. There is no limit on the number of times you may do this type of transfer, providing you follow the rules I describe later in this section. That means hobbyists who like to tinker with PCs can relax. If you buy a System Builder copy, you can move (not share) that license from an old PC to a new one.
Well, even in the OEM / System Builder versions of Vista, 7, etc. You could call MS up and tell them you upgraded your motherboard. They will activate it for you. As the post above suggests, they have officially relaxed it.
