Bluetooth driver issue in Windows 8.1 fresh install

Hi all, I freshly installed Windows 8.1 Pro x64 in an SSD. I'm still using Windows 7 x64 until I can sort out some issues. In Windows 7 Device Manager under "Bluetooth Radios" I see a single line labeled "Bluetooth module" (Broadcom driver version 6.5.1.1061). In Windows 8.1 under "Bluetooth Radios" I see 3 lines listed, "Bluetooth module" as with Win7 (Broadcom) plus two Microsoft items (Bluetooth Enumerator and I forgot the other one). Is it fine for the Microsoft and Broadcom driver to coexist or should I keep only one? If so which one? I tried disabling/uninstalling the Microsoft one but it keeps coming back. Thanks

P.D.: In Windows 7 if I want to turn On/Off the Bluetooth Adapter, there's a bluetooth icon in system tray that I can right click to do this. In Windows 8.1 that same icon also shows in system tray but when I right click on it the option to turn it on/off does not show up. I guess the only way to do so is to go to NEtowrking/Change Adapter Settings and disable it from there. Weird.

No there is no problem - just leave them like that. If you have a special key combination (e.g. FN+F2) you can enable/disable like this.
