Wireless Apple Trackpad does not work with Windows 10
I have installed Windows 10 via Boot Camp on my iMac with iOS Sierra. My Apple Trackpad works perfectly on the iOS side, but cannot be installed on Windows 10. It asks for a "passcode" which should be on the device or in the literature of the device, however, there is none in either. Right now I am using a wireless mouse with Windows 10, but I would prefer to use my Trackpad. Any suggestions?
iMac, iOS 10.2.1
