After a ton of problems (pretty much all on my part) with the Windows 8 demo on my desktop, and a fully working demo on my laptop (hooray!) I've decided to break down and buy Windows 8. The problem is, my aforementioned problems on my desktop completely corrupted my OS. I had a friend confirm that if I buy windows 8 with the disc and put this into my desktop, it will install on my computer. The only problem is that I can't find a single place in the Microsoft store where to buy a full version of Windows 8 or Windows 8 Pro. The only things I see are downloads/CD's of a Windows 8 Upgrade, and while I see a full version on newegg, I'd rather get the software straight from Microsoft. Any help would be greatly appreciated, and thanks in advance.
