For security purposes, please do not install iTunes on your Windows 7 PC. Apple, for some reason has implemented a feature called "Autorun" in the iTunes program. This autorun will allow a virus to spread rapidly, especially in a networked environment. If you are running Vista, Windows 7 and have iTunes installed, for your own protection and the security and health of your PC, please remove it. Personal experience, other people having said issues on many forums and various articles from the web.
