In Windows, how do I see all listening network ports?

[ShiftPoint]

In Windows, you can use the netstat.exe program to view all listening network ports. To do so, from a command prompt, type netstat . You can use also use options to get more information, as in the following examples:

netstat -o Show the process IDs (PIDs) associated with each port
netstat -a Show all
netstat -n Show numbers of ports

You can also combine options, e.g., netstat -oan .

Netstat FTW! I use it to determine if there's a virus/malware running in the background.
