You'll also need to install another application to allow the new trackpad driver to be installed, but it's worth it. The developer's website looks straight out of the 90s and not terribly trustworthy, but he has a strong reputation, and the driver was recently updated for the 12-inch MacBook and Windows 10. I didn't actually have it installed on my old Mac's Windows partition, but I highly recommend installing it now. Years ago I discovered Trackpad++, a driver solution to bring the functionality of Apple trackpads closer to how they behave on OS X, and closer to how high-end trackpads now behave on Windows. Apple still curiously doesn't provide a Bluetooth driver in this driver package, but everything else works.

I rebooted and chose to re-run the driver installation after 'troubleshooting compatibility', where Windows recommended that it skip the forced version check. The all-important system tray application for modifying trackpad settings and quickly booting back into OS X also wasn't present. For example, I was able to modify volume with Apple's native UI popup, but brightness (which uses the built-in Windows switcher) didn't change. Unfortunately, not every driver installed successfully the first time around. Fortunately, upon finishing the installation, the Boot Camp drivers were automatically recognized on the USB drive and installed, which is what is supposed to happen. If you've ever installed Windows 8.1 on a Mac, you'll recognize the process not a lot has changed. These saved to an external USB drive that I left plugged in during the installation. I did, however, make sure to re-download Apple's latest Boot Camp drivers through Boot Camp Assistant before installing. I opted to install from Windows 8.1, which still installs a fresh copy of the operating system, but it's easier than creating installation media from scratch. I wanted to record a few thoughts about it for others curious about the new OS, especially its usability and performance on this new hardware. But after taking the plunge, I'm very happy to be using it. I had tried it out a couple months earlier through a virtual machine, and at the time I wasn't sure I wanted it as my main operating system. I've had a remarkably good time using it so far, and just yesterday I decided to upgrade my installation of Windows 8.1 to the Windows 10 Insider Preview. I've owned the 2015 MacBook for just over a month now. Update 5/15/15: I've clarified some of my findings at the bottom of this post.
