I tried to follow these steps to install the driver in my windows XP: http://www.labnol.org/software/apple-magic-trackpad-with-windows/14158/ I can install the driver in XP, detect the trackpad. There is "bluetooth HID mouse" in the hardware management, and I try to update the driver. I can select the tracpad driver but the windows say cannot successfully install. I tried different ways but the best is just using the trackpad without right click or two fingers, just simple one click. Anyone have luck successfully install trackpad in Windows XP? Welcome to show me how if you know.
