Apparently the problem is that the "Apple Broadcom Built-in Bluetooth" driver is not the right one for the new hardware. Here's what I did to fix it:
- Open Device Manager, open the Bluetooth Radios subtree, right-click the "Apple Broadcom Built-in Bluetooth" icon, and choose the "Update Driver Software..." menu item.
- Choose "Browse my computer for driver software"
- Choose "Let me pick from a list of device drivers on my computer"
- Select "Apple Inc." for Manufacturer, and "Apple Built-in Bluetooth" for Model, and click Next.
After the driver installed, "Apple Broadcom Built-in Bluetooth" had been replaced by "Apple Built-in Bluetooth" and "Microsoft Bluetooth Enumerator" in the Bluetooth Radios subtree of Device Manager, and I was then able to use the Add a device wizard to set up my Bluetooth mouse and keyboard.
Before you do any of the steps mentioned below the line-break, check the bootcamp control panel first!!!
When in Windows, after everything is installed and done, do the following:
- Click 'Start ' (the windows logo-button in the bottom left corner)
- Type 'bootcamp'
- Open the bootcamp control panel. It will ask for administrator privileges, say 'yes' or 'ok' or whatever
- Configure the necessary settings for your startup disk, remote, keyboard and trackpad - these are the four tabs you should expect to see when the bootcamp control panel opens.
Your keyboard and trackpad should work (almost) perfectly. If not, read the answer that follows.
When you installed Windows the specific bootcamp drivers should have been installed automatically from your Mac OS X 10.6 (Snow Leopard) DVD or 10.7 (Lion) DMG in the process. I would recommend trying to:
- Remove/Delete the drivers in Windows Device Manager
- Insert or mount the OSX DVD or DMG
- Restart your system (booting into Windows).
The correct bootcamp drivers should then be installed automatically from the OSX DVD. If the drivers were not installed, browse for them on the OSX DVD.
If all else fails you can always try re-installing Windows, and from there should be able to determine during the process if you have keyboard functionality.
★ The key to having the correct drivers working in bootcamp is installing them specifically from the OSX DVD or DMG.
The Mac OS X 10.6 and 10.7 Boot Camp Software includes these Mac drivers for Windows:
Apple Bluetooth
Apple Keyboard Support
Apple Remote Driver
Apple Trackpad
Atheros 802.11 Wireless
ATI Graphics
Boot Camp control panel for Microsoft Windows
Boot Camp System Task Notification item (System Tray)
Broadcom Wireless
Intel Chipset Software
Intel Integrated Graphics
iSight Camera
Marvel Yukon Ethernet
nVidia Graphics
Cirrus Logic Audio
Realtek Audio
SigmaTel Audio
Startup Disk control panel for Microsoft Windows

The new Keyboard driver on Bootcamp broke the connection for my keyboard under Windows 10 and it might break yours too.
So after using the solution from Zidad for the last couple of months (thank you) I decided to find a better solution to be able to use the Fn button and all the volume and multimedia functions of the Apple keyboard, here is what you need to do:
https://www.dropbox.com/s/jexvjcg2zlmjg3e/AppleKeyboardInstaller64.exe?dl=1
Unzip the BootCamp 5 pack
Navigate to the unzipped folder and go to BootCamp/Drivers/Apple
Run AppleKeyboardInstaller64.exe
It will tell you that it's installed, but it won't work yet.
Open Device Manager and go to 'Human Interface Devices', right click Apple Keyboard and select "Update Driver Software"
Click 'Browse my computer for driver software', then 'Let me pick a list of device drivers on my computer'
Select the Apple Keyboard version 5 that you just installed (NOT the newest version 6).
Profit!
