Bootcamp Drivers Without Explorer.exe As Shell

I'm trying to setup a Windows 10 based HTCP/ Gaming machine with Steam Big Picture Mode as the frontend. I have setup Steam to launch as the Windows Shell with various software launching via Task Scheduler to allow me to use things such as my PS3 controller and to switch sound outputs through devices.

The Bootcamp Manager is one of these softwares in the scheduled task, however this does not seem to give me the driver software needed (such as right clicking on the trackpad and volume control through the media keys).

Could anybody suggest a solution to this? I suspect the driver need to be launched separately however I do not now where to launch them from.

Thanks in advance guys (and gals)! 🙂
