I think I have a deja-vu about this. Hasn't something similar been posted in the past(like months ago..)?
Did anybody buy back then?
OP, can you give us more proof that these are indeed genuine keys and are not hacked?
I see you accept escrow, that's great actually. I'm more concerned that the keys might be obtained through noughty ways, that's all.
Also, I may be interested in a Windows 7 ultimate key.
Well this is the first time I have ever been on this topic so I don't know.
They're obtained using a MSDN account so they're not cracked or stolen in anyway, all genuine. You receive everything the same as if you bought it from the shop.
This is the best proof I can provide of my account :

It says that next to every product but I can't show you since I have generated some already and it shows them.
