Apple Wireless Bluetooth Keyboard – pairing with Windows 7
One of the greatest frustrations I have had with using the Apple Wireless Bluetooth Keyboard with my Modbook is that it sometimes gives out inexplicable error messages when trying to pair with Windows 7 and refuses to go forward with the process.
I was able to find an article on the net (forgot the link, unfortunately), explaining why and how to deal with the problem. It turns out that if the Apple Wireless Keyboard got paired with OS X, it needs to be unpaired from OS X first. Otherwise, for some reason (it keeps wanting to be with OS X ?) it will fail to pair with Windows 7. Remember, this means that the Apple WIreless Keyboard not only needs to be disconnected but also unpaired. You should be able to do this by clicking on Bluetooth in the System Preferences, selecting the Apple Wireless Keyboard and clicking on the “-” button at the bottom. This should both disconnect and unpair the Apple Wireless Keyboard.
Driver-wise, you should ensure that you use “Apple Built-in Bluetooth” under “Bluetooth Radios”, and then install the Apple Keyboard Driver from Boot Camp in that order. If you can’t get them work, uninstall these drivers and reinstall them in the proper order.
