I am running Windows 10 on my late 2009 iMac and just bought the Apple Magic Trackpad 2. While it works perfectly in OSX, it has minimal functionality in Bootcamp (Windows 10). It moves and left clicks only, all other functionality is missing, including the ability to right click. I suspect there is a driver to resolve this issue, however I am yet to find it, and I do have Bootcamp 6.0 installed, and have performed a repair with no resolution to the issue. I also downloaded and tried the third party solution Trackpad ++ to try and add the missing functionality, however that solution errors out and states that the hardware is yet to be supported. I will continue to look, but unfortunately, there is little published on the internet thus far about the Magic Trackpad 2 and Bootcamp/Windows 10 drivers.
