My W10 Home says it doesn’t support RemoteDesktop. I always disable any program that would allow another PC to connect...
If your PC is connected to any network, wireless or wired, another PC can connect to it. More common protocols like RDP are just what the public understands. RPC, DCOM, and WMI are examples of other Microsoft protocols that allow access to your computer remotely, but they’re more secure than RDP in some ways.
