I had a look at Windows 10, by default, assuming you clicked Private for the network connection, there are no ports that are open for any program to use. There are 33 rules for the All profile, 18 for the private profile, some duplicates, each of which specifies what local program is allowed to receive data: 9 connect to Modern Windows apps, 1 for ICMPv4, 12 for ICMPv6, 1 for IGMP, 1 for ISATAP, 12 for TCP, Cast to device, IPHTTPS, Network Discovery, WiDi. 15 UDP: 2 for Cast to device, 2 for DHCP, 1 for Teredo, 1 for Delivery Optimization, 1 for mDNS, 7 for network discovery, 1 for miracast.
