Right now I have Windows Xp and I thought it was time to upgrade my computer to Windows 7 but when i looked for the operating system there were posts that said Windows 7 Ultimate – Upgrade and
Windows 7 Ultimate – Full. Is the upgrade only for Vista? Which one should i get?

I have Windows Vista right now and want to upgrade and I saw both windows 7 and the windows 7 starter to home premium, but one is 30 dollars cheaper. Whats the difference between them?

Hello, I just bought a new Windows 7 PC for my personal use at home and have set up a secondary user account for my girlfriend to use. The problem I am running into is programs which I’ve downloaded (i.e. Chrome, Firefox, AIM, Gtalk, etc..) do not appear when she is logged in. Is there anyway to get them to show for both user accounts without my having to download and install them twice? Thanks!

i currently have windows 7 home premium, and im thinking of upgrading to windows 7 ultimate. could some one please tell me how i would be able to downgrade to windows 7 home premium if i am not satisfied with windows 7 ultimate?
