The part after the symbol ':' gives the PORT number.
You should get something like IP:PORT in both the columns.
the foreign address shows port 80 status s established. how do i get more info/kill that process.
You could add the switch -o to list the PID of the process and -p TCP to list connections for the protocol TCP. Adding -b or -v may also be useful.
netstat -anop TCP
netstat -anopb TCP
Can't say how effective is killing a process in windows. However, you could give a try to taskkill or use TaskManager.
taskkill /PID 1234
As always try adding /? at the end of the command you need help with and you will find some option you may be searching for.
