Although I'm new to these tools, I installed Wireshark and Nmap. I was doing some learning on Wireshark and the tutorial called to use the command nmap localhost at the command prompt in Windows to see what ports are open on your system. This guy had two ports open, when I did the command I have literally hundreds of ports listed as belonging to one application or another. rpc somewhere, Elite, sql, iPhone-sync, rxapi,... The list goes on, literally just hundreds of entries. Are these ports all open for use by these services? On Windows 10, if they're open, how do I close them?
