Guys, just to follow up. DO NOT buy any software from eBay. Luckily I did my research and no! It's mostly Chinese fakes. Search YouTube for Windows 7 Ultimate fake key and it will come up with a bunch of videos. Most people say that their copy on Windows bought off eBay activated and worked for about 6 months and then Microsoft canceled the registration key. At which point they can't return it anymore. And unfortunately there's no site that Microsoft provides that could let someone check if a specific product key is valid or not.....

So yeah, I'm stuck! Will have to probably go with Windows Server 2016 Essentials. It's $560. Ouch!
