Help ! Since I installed the October hardware update this morning e I no longer have a working physical keyboard on 8.1. I have tried both the wireless one connected through my dock and a Surface Keyboard attached directly to the machine, neither work ! Tried installing the Microsoft Keyboard and mouse centre, rebooted multiple times and still no keyboard. Both work fine if I boot in to 10 technical preview that I have installed in a partition for dual booting. Anyone else getting this ?
