I have built a computer and need to install an operating system. (I built it a month ago and haven't gotten around to it) Anyway I was planning on buying windows 7 but no where in my area sells it. So i have now convinced myself to just use windows 8 but, I cannot find any. All the places I have been to have Upgrade packs or windows 8 pro upgrade or something? Is that what I should get or what? Personally I wish i could stick with windows 7 but, oh well. So what do I buy?
