Re: [WTS] Microsoft keys, Windows keys, ... (Best price ! legit keys, NOT FROM MSDN)

Where are they from if they are not from msdn?

I can't tell bro but they absolutely are not from MSDN, you can check them using this app : http://janek2012.eu/ultimate-pid-checker/ when you have key.

Where specifically does it say they are not from msdn in that tool?

Key type will show "MSDN" instead of "Retail"
