I'm curious about "System" usage of these ports. What executable is "System" and why is it on these ports?

Use Windows' "netstat -an" command. It tells you which ports are LISTENING on the internet. You need only be concerned with listening ports. The other ports that are not marked as listening are for local use.

445 is used by Windows and is commonly open.

5101 was identified in your earlier scan as Yahoo Messenger.

1027 was identified in your earlier scan as Firefox.



try netstat -abn

It'll list the processes.
