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?

Attaching a debugger to the BootCamp control panel, one can see that the settings are written with an
IOCTL
of the formatCTL_CODE(FILE_DEVICE_MOUSE, 0x801, METHOD_BUFFERED, FILE_ANY_ACCESS)
. The data written matches what is found in the Windows Registry atHKEY_CURRENT_USER\Software\Apple Inc.\Trackpad\Mode
. I've determined the format of this entry to be:I wrote a quick program that will read this registry entry and write the settings to the
\\.\AppleWirelessTrackpad
device. Download it here (source code available, contributions welcome). Someone with Windows programming experience could add a nice UI and have it run as a service to detect and initialize when the device is [re]connected.For my personal setup I manually changed the registry setting (0x6b: defaults, minus drag lock!) and run this program as a Windows Scheduled Task (at login). On the rare occasion that the pad loses sync between reboots, I just run the program again manually to refresh the settings.
Here is a sample registry file, save as plain text then double-click to apply:
