Windows 8.1 and Apple Bluetooth Mouse and Keyboard connection

I recently upgraded to Windows 8.1 from Windows 8.0 Home and as a result I'm experiencing the following problems:

• Apple Bluetooth Mouse - randomly dis/connects or freezes where I cannot move the mouse or it's very jerky or very slow.
• Apple Bluetooth Keyboard - the keys will stick or freeze causing the redundent key presses (eg. yyyyyyyyeeeeeee).

I've done the following to fix the problem with no success:

• Reinstall Boot Camp 5.0.5033 drivers
• Reinstalled Bluetooth drivers from Boot Camp 5.0.533 individually
• Unistalled both devices on OS X and reinstall them only on Windows 8.1
• Reinstalling both on OS X and reinstalling them on Windows 8.1
• Uninstalling all the drivers from the Device Manager and reinstalling them

One thing I have noticed is that under Devices and Printers I have two new devices (HID-compliant mouse and HID Keyboard Device) that were not there under Windows 8.0 in addition to my bluetooth devices. I have tried removing the new devices but they keep reinstalling themselves.

I have USB mouse that's connected and I've been able to use that without problems so I think there's a problem with the Apple driver or the Windows 8.1 bluetooth drivers.

Has anyone fixed this?

Thanks!
