We are getting really close to having a Windows version for Windows Mobile, Surface, etc. I'm personally using it on a Windows 10 PC. The software is pretty much there, we are ironing out the deployment to devices and subscriptions.
suspect, barring any major delays, this will be for early 2016, hopefully in time for SnF or earlier. We are currently focused on 9.4 right now and some new device integration like the Dual XGPS 190 and Bad Elf project amoung others. It's really close now.
