It's going to be used in a workstation, so it has to be both Windows 7 and not pirated.WTF?!
Try this site for something better...

Otherwise, if I were inclined to use pirated software, I certainly wouldn't pay for it.
I just used this.
You do realize that's an obvious scam site, right?
The guy that created that site apparently owns about 850 other scam domain names as well. I hope you used a single-use disposable credit/debit card for that purchase! (and be prepared to buy a real license key once Microsoft shuts down the illegitimate key you are using now...)

I dont think MS will ever catch on. Thise keys are legit, they were just never meant for resale. There are probably hundreds of thousands of them out there, how would MS know they were resold?
Nah, they are either generated by hackers and will not pass prolong Activation, or the seller bought few legit keys and simply sell the same few keys to hundreds of "Wishfull (and not so smart) thinkers".
After a while the existence of these duplicate keys is registered on the Activation severer and eventually they get deleted from the server data base and Windows suddenly comes with the fraud screen.
Why not just use windows 8?
