Yeah, I have 2 questions about Win7. First, I can change my Wallpaper with the Admin to whatever I want. But when I go to the other User, I can only change the Wallpaper to a single color, if I try a picture or pre-installed Wallpapers like the Windows Aero wallpapers it changes to black. The second question is, if any data will be deleted or damaged if I use Windows Anytime Upgrade, because I found out that it is easy to find free Windows 7 Keys and I want to upgrade to Windows Ultimate 64-bit or Pro 64-bit because I'm stuck with Win7 pro 32-bit(my processor supports 64-bit)
