Yes, I wondered about that. But in the past MS record keeping has been very accurate. If it had been one person, that would have been weak, but two...I don't know.
The thing is, so much this soft is being sold every day. I would suggest most builders use OEM. They can buy an entire computer with W7 on it, for the cost of a full version. I raised this with NewEgg and they promised that a senior person would be advised.
It's all to do with the fact that the old description of possible users has now gone. The old one contained the word "Assemblers", which may or may not have been the justification.
CompUSA told me that they sell it all day long with no comebacks. They're the ones that state that there is no difference apart from the packaging and that you only get one bit-version. They talk a lot about how green it is to not have the posh packet.
