Anyone know how to modify settings for the Apple Magic Trackpad on Windows (without Boot Camp)?

I was able to install the driver and make it work.

However, tap-to-click appears to be on by default, and I think this would work much better if I could turn that off.

The problem with just installing the drivers is you don't get the Boot Camp control panel so you can't adjust settings.

Has anyone figured out where the settings for the trackpad are stored?
