I have played a little with Windows 10 on Raspberry Pi 2 over the weekend. The good news is that yes, it allows device drivers installations and etc…
Regretfully devcon is not suitable for installing network filter drivers and since there is no GUI control panel applet then a port of snetcfg is also needed to install NDIS Lightweight Filter Driver. It was not a big deal to compile WinpkFilter for ARM, but simple compilation of snetcfg for ARM did not work and it needs more time to resolve.
