Today I finally got up my plays before weeks WIN 7 software. At first I was very suspicious, because the software comes from Dell. After I had the hard drive removed by formatting WIN XP, I started the installation. Everything went smoothly. Even the activation of Windows 7 at Microsoft was done easily online. In the dealer's manual was thought that a telephone activation in MS is necessary. But the better + the accompanying Product Key Dell also worked with no complications. WIN 7 runs great - because I'm crying my otherwise so beloved XP no tears afterward.
