To download and install the latest boot camp drivers for windows, you need a 16 gb or larger usb 2 flash drive. (usb 3 flash drives don't work when installing windows with boot camp.) it will be erased, so back up any of its data that you want to keep before continuing.. Ran into same issue with windows 10 ver 1511 running on mac mini late 2012 with the new boot camp 6. i found that if i went to the windows control panel under bluetooth then unpaired / repaired and reconnected that the magic mouse and keyboard would work consistently.. And another funny thing: apple magic mouse and keyboard work fine under windows 10 (except for the scrolling function of the magic mouse). i read the other threads. essentially, the message was: "we have to wait for the next bootcamp drivers from apple"..
