I've used this key for over a year and have installed/reinstalled windows at least 10 dozens times on a plethora of different machines. Anyways, for what it's worth, I don't know if it's legit... I just know it works.
So in other words, you are selling a pirated key for $60?Quote
I'm not a scammer
Some might disagree - certainly the OP who specifically requested legitimate licenses for a client. Microsoft might also deem you a scammer.
[Edit] And offering to sell pirated Microsoft keys from a traceable account name? Seriously?
