Razer Edge Pro (2013) - volume rocker and windows button

Hi, I have had Windows 10 on this device for a while now - everything works well apart from 2 things: 1) Volume rocker (nothing happens when you press up or down) 2) Windows button doesnt work Has anyone got drivers for Windows 10 to pick these 2 buttons up? they worked in Windows 8 & 8.1 - then after the upgrade to Win 10 they dont work Thanks in advance Nick
