Through my school I can get Windows 7 or 8 (upgrade versions) free. I have XP running on my desktop PC and was thinking about installing 7 or 8. I'm not sure which I want to go to. I haven't used 8 much at all and a lot of people are saying the start menu is cumbersome and they were sticking with 7. Also I've never installed Windows using an upgrade disc. I have a licensed version of XP and plan on backing up my files first. Anything else I need to know about? Wanna kill these ads? We can help!
