Here is my experience on Windows 8:
From: Pinky
Dolphin: 3.0-867-dirty
Wiimote: Nintendo Wii Remote + Nintendo Motion Plus Adapter + Nunchuck
Brand: Nintendo
Bought from: Pre-owned from GAME (UK) Total cost was £37
Bluetooth ID: Nintendo RVL-CNT-01
Bluetooth: BELKIN - F8T016NG Mini Bluetooth Adapter (using the Microsoft bluetooth stack)
Brand: Belkin
Bought from: Currys £8
Sensor bar: Candles at the moment as am waiting on my wireless bar arriving
Bought from: I found them in the cupboard, god knows where the candles were bought from
OS: Windows 8 Pro with Media Center 64Bit
Working: Works well, no issues in game so far.
Not working: If batteries run out or remote turned off, you may have to remove the device in bluetooth and re-pair. Sometimes involves a re-boot of the OS in order to do this properly.
Resolution to re-pairing issue: Used Wiipair - I need to do more testing but both taking the batteries out and re-booting the OS did not lose the pairing and the wiimote is ready to use - http://www.richlynch.com/code/wiipair
Notes: The Belkin USB bluetooth adapter doesn't appear to work in a USB 3.0 port, so make sure you have a spare legacy USB port free in order to use it. Didn't use the Belkin drivers, just put in the USB bluetooth adapter and let windows install.
