This was what Brad at Rose Point had to say on this matter last July and I don't think things have changed since then:
"However, there is one thing that Microsoft has removed from Windows 10 that was in Windows 7, 8, and 8.1 that might affect some Coastal Explorer users. That is the ability for a Windows Desktop
App (such as Coastal Explorer) to use the "Windows Location Service". This service
provides a way for apps to share a location sensor without connecting directly to a GPS though a "Communications Port". This usually meant position estimates from Wi-Fi hotspots and cellular connections, and in some cases a GPS built into a tablet or laptop
These positions tended to be very rough and we've probably had more customers ask how to disable Coastal Explorer's use of the Windows Location Service
than customers actually using it, but it's worth mentioning that in Windows 10, it just won't work at all (at least for now...Microsoft may change its mind later).
As far as we can tell, Windows 10 and Coastal Explorer will continue to work with all of the other devices that have worked in the past; just not the Windows Location Service."
