Ok I have windows vista but I want windows 7. So I am planning on getting windows 7 on release date. Now I have never upgraded a computer before and I just bought my laptop in august 2009. How do I successfully upgrade without losing my stuff like:
Sims 3 data, Office and school documents, music for Zune HD, and programs I downloaded to my computer.
Can I just upgrade and everything will be fine? Please help!
