Anniversary update stops Xbox media remote from working?

Hi,

I control Kodi on a windows 10 HTPC using a XBox media remote (ehome driver) and a receiver from an old microsoft media centre remote. It’s always worked fine with Kodi, however after the anniversary update got applied, the remote stopped working. If I roll the update back, it works fine again – so it’s definitely the update causing problems. After the update, there are no problems listed in device manager. The problem doesn’t appear to be Kodi specific, since ‘Showkey’ doesn’t show any action when I press remote buttons, even though the red light on the receiver lights up. I read that the anniversary update resets the registry keys for what buttons do what, but I tried backing up & re-applying those settings after the update, to no avail.

Any ideas?
