I also use Avenza, and it does work on my PC with Win 10. That's not real useful, since my PC doesn't have a GPS, but on the other hand if you want to print a map the PC can do that easily. The beauty of Avenza for me though is that it uses the GPS to show me where I am on the map, and it doesn't need to be connected to the network once you've got the map. The major complaint I have with Avenza is that if you are not within the boundaries of the map you are looking at, it will not show you anything to reference what direction or distance you are from that map. Takes a little planning in advance before you can make use of it.
What is outstanding about Avenza for me as a boondocker is using it with BLM maps. Makes it easy to see when you're in a dispersed camping area.
