I ran both resets but didn't notice anything new on device manager.
I played around with an unspecified device on device manager and was able to get the Bluetooth radio back up and running. However, now back to square one where I can't seem to switch the driver from the default Windows driver to the Apple boot camp bluetooth driver. No matter how many times I uninstall the Bluetooth driver and the trackpad, I can't seem to permanently disable or uninstall them. Right now, I have Bluetooth support services disabled to try and prevent Windows from automatically installing Windows Bluetooth drivers.

I also have disabled automatic download of manufacturer apps and custom icons under "device installation settings." Somehow I seem to have stopped the automatic installation of Windows drivers. But even with this in place, nothing happens after I run the boot camp set up again to try and reinstall Boot Camp drivers.
I tried right clicking on the Bluetooth radio --> update driver --> browse my computer for driver software --> search for drivers in this location --> select D:\WindowsSupport\BootCamp\Drivers\Broadcom, but this doesn't work.
I also tried right clicking on the Bluetooth radio --> update driver --> browse my computer for driver software --> let me pick from a list of available drivers on my computer --> have disk, but even if I navigate to D:\WindowsSupport\BootCamp\Drivers\Broadcom, it won't let me select anything because it looks like it requires file type .inf
Finally, I tried right clicking on the Bluetooth radio --> update driver --> browse my computer for driver software --> let me pick from a list of available drivers on my computer --> uncheck "show compatible hardware" --> "Apple broadcom built-in Bluetooth version: 6.1.6700.0 [10/4/2016]. The installation was unsuccessful. Here's the screenshot after this method. As you can see, that driver isn't functioning. My trackpad is also still somehow registering as a hidden device, even though it has been uninstalled, isn't on, and isn't even paired on the MacOS side.

Any other suggestions?
