I bought 2 Windows 7 Pro keys from softwareseller. Both activated without issue. From my long history of dealing with keys of this exact nature, I do not expect to have any issues at all. Like I said earlier, the only trouble you will have with these keys is if you try to use them on two machines.

The other issue you MAY have is if you wait too long to use them. MS seems to be willing to deactivate keys if they have not been used, but I have never had them inactivate one of these keys that has only been used on one machine.

I bought also some keys from softwareseller.
Till now everything worked fine and he also gives additional support and fast answers. So if i see anything interesting, i will again buy! i would say:
stop spaming and attacking his offers. If you want to buy, write him, if you do not want to buy, go ahead and read other threats...

Thank you for your good offers and the support. looks very good till now.

btw i bought office, kaspersky, win8 and win7
first 2 i already tried, last 2 i will soon, but i have no fear that they will not work, he seems to be fair and trustfull till now.

sorry for bad english, could be better i know
