That isn't legit ^ Those are technet keys and will become non-genuine
What's legit and what's illegal with Windows is pretty confusing so forgive my ignorance. What's a technet key and why would it become non-genuine?
MS TechNet. A subscription service from Microsoft, whereby (for a fee) they give you access to LOTS of software and accompanying activation keys. This is for an IT department to test various deployments, operating systems, and applications.
You get multiple keys to just about everything MS sells.
NOT to be used for a production environment, or as a substitute for buying a retail or OEM OS version.
Say I have a small dev shop. 8 people. I can create many OS installs for testing a web application before putting it online. Things work differently from XP to Win7 to Win8. I can test in my internal environment on all those platforms.
The TechNet concept is going away August 31 this year, specifically because people would buy a $250 license, and then sell the keys repeatedly.
Eventually, the key that you, the unsuspecting buyer, may get is identified as being used far too many times, and is then deauthorized. MS can and does track by frequency and activation location.
The seller does not care, because he already has your money and has moved on to a new eBay seller account. You, the unsuspecting buyer, are out of luck and money.
