apple wireless keyboard win 10/x64
I run a mid 2013 MBA plus cinema display plus apple wireless keyboard (model A1255). This constellation worked fine both under MacOS (currently 10.11.5) and bootcamp win 7-64. Recently, the system began to "forget" about the wireless keyboard, which could be re-connected, sometimes automatically (after deleting all the drivers and reinstalling them (which, incidentally, even resulted in a windows blue screen which was recoverable from by simple rebooting)) and sometimes manually by keying in the automatically generated code number.
In view of the availability of win 10/x64, I decided to upgrade. Everything runs fine now, but the wireless keyboard is not connectable at all any longer.
Right after installation of win 10 via the official bootcamp routines, I got a notification about a faulty driver. Still, the system offered me even a keycode to connect to the wireless keyboard, but did not give me enough time to key that code actually in. Thereafter, I got stuck at the point where the keyboard is reported as coupled, but upon trying to actually connect it the window for keying in a code pops up (with no code generated automatically) and at that point all attempts fail (i.e. "0000" "000000" etc.).
I uninstalled the keyboard drivers and put in those from earlier bootcamp versions - no change. The bootcamp I used is 6.0.6136. I also uninstalled the bluetooth drivers - no blue screen with win 10, but otherwise unsuccessful as before.
I wonder whether the keyboard driver is relevant here at all - perhaps this is the driver for the on-board-keyboard of the MBA? In any case there this just ONE keyboard driver in the device manager listed, not two, as one would expect. It also could be that the bluetooth drivers are not compatible although they work fine with the wireless magic mouse and other bluetooth items. I also note that a driver shows up under bluetooth drivers for that mouse - but there never was something like "Apple Wireless Keyboard Driver".
Help, Apple! I need that keyboard!
