Microsoft Bluetooth enumerator reappears after removal from device manager

I have a device that will only run using PC software. It can be connected via USB or Bluetooth. I have a preference for BT as it reduces the amount of cables required when working away from a desk. It works with XP SP2 and runs well under Bootcamp. If I remove the Microsoft Bluetooth enumerator from the device manager and leave only the Apple BT driver all is okay I can communicate with the device. When I restart the computer in Bootcamp, Microsoft Bluetooth enumerator reappears in the device manager and I again cannot communicate with the BT device. Is there some way to remove the Microsoft Bluetooth driver permanently?
