So I found a bunch of Windows serial keys and I have no idea if any of them work. PM or comment which OS key you want and I'll hopefully send a working key. No promises. If you get one that doesn't work, sorry!
Keys for:
Windows 7 Starter x 3
Windows 7 Ultimate x 15
Windows 7 Home Premium x 36
Windows 7 Professional x 15
*I'll update this as they're taken
