The Problem

As yet (5th Aug 2015) there’s no official support from Apple for Windows 10 running through Boot Camp. So, when I upgraded from Windows 8.1 to 10, I was expecting there to be a couple of issues. One of these was a lack of Bluetooth. Also getting the fn key working.

But, it turns out to be easy to fix.

Get the Driver

The driver for Windows 8.1 works with 10, so you just need to grab that.

Go to https://support.apple.com/en-us/HT204048 and find your machine in the list. You want to look for the zip file download of the Boot Camp Assistant software.

For me, it was this one:

Download that file (it’s pretty big – 882Mb for my one) and unzip that once done.

Install the Driver

Inside the unpacked folder, go into the BootCamp folder and then into the $WinPEDriver$ folder under that.

The driver needs to be installed via device manager so just confirm that the AppleBluetoothBroadcom64 folder is there for now.

In Windows, open up device manager (the easiest way to do this is just hit the Windows key and type ‘device manager’ – it’ll be the first result).

Expand other devices and you should see an unknown device.

Right click it and select Update driver software.
