You have to check the "Edition-ID" on google and you will find out if they are from MSDN. OP washed out these numbers so he is hiding something, I can tell you 1 thing for sure: these are not retail bought key's legit from a real store. Watch out.
Thanks for your feedback. Yeah, and the bummer is my trust (and the trust of others) got absolutely destroyed because of honesty. Everyone here is selling MSDN keys.
