Suspect RemoveWAT was used to make used computer appear valid

Good job calling this vendor out Christy. It's hard to say how much a OEM w7 in bulk would cost. I suspect one can't even buy any now though.

Refurbishers (real ones) get a marked discount over even OEM System Builder, I believe - but there are strict rules over how such licenses can be used. They are currently using Windows 7 for refurbs, since XP was withdrawn from the chain over a year ago (I think the change happened when Win8 was released but I'm not sure)

MS is still supplying OEM System Builder licenses and packs to OEMs - but they haven't sold any Retail licenses since the launch of Windows 8.
This is their normal practice.

Apparently MS will allow OEMs to sell w7 machines to consumers until Oct 14, 2014. Microsoft extends date for OEM preloads of Windows 7 for business users | ZDNet
For business use, a little later.

..and refurbs are a whole different ballgame altogether :)
