I am building a computer soon, and I would like to use Windows 7 as the operating system. However, I don't know where I should purchase a copy, as many on Amazon, Newegg, etc are out of stock or overpriced. So is there a good place where I can purchase a LEGITIMATE copy of Windows 7 that isn't overpriced? I don't want to risk getting some cheap or even free copy of an OS.
Thanks!
