Start-run--cmd Enter the command prompt input Netstat-ano to see all the connected PID after the PID in the task Manager to find the corresponding program if the Task Manager does not have the PID , you can choose "View"-"Select column in Task Manager" "

Often, we start the application when the system needs to find the port is occupied by other programs, how to know who owns the port we need, a lot of people are more headache, the following is a very simple method, we hope to be useful

If we need to determine who's taking up our 9050 port,

1. Windows platform
Execute under Windows command-line window:
1. View all port usage

c:\>Netstat-ano

2. View the usage of the specified port
c:\>netstat-aon|findstr "9050"

Protocol local address external address state PID

TCP 127.0.0.1:9050 0.0.0.0:0 LISTENING 2016

P: See, Port is occupied by process number 2016 process, continue to execute the following command: (You can also go to the task Manager to see the PID corresponding process)

3. View the PID corresponding process
c:\>tasklist|findstr "

Image name PID session name Session # Memory usage
========================= ======== ================
Tor.exe Console 0 16,064 K

P: Well, it's clear that Tor is taking up your port.

4. End the process

c:\>taskkill/f/t/im tor.exe
