Bluetooth drivers unable to install

I recently bought the Bluetooth USB adapter usb-bt4le and I want to use it with my RPi3. I have windows 10 core IoT installed on the RPi. I have disabled the on-board bluetooth and I wish to use the usb bluetooth for communicating with the RPi. I wish to know how to install the bluetooth drivers on the RPi. Your site mentioned that windows installs the drivers by itself but it doesn’t seem to be doing that. I tried downloading the drivers from the website but that isn’t installing the drivers either. Is there something I am missing?
