In Windows, how does one view port usage?

Start -- run-cmd

Enter the command prompt

Enter netstat-ano to view all connected PID

Then find the corresponding PID in the task manager.ProgramIf the Task ManagerNo PIDYou can select "View"-"Select column" in the task manager"

Often, when we start an application, we find that the ports required by the system are occupied by other programs. How do we know who owns the ports we need, the following describes a very simple method.

If we need to determine who occupies our port 9050

For Windows, run the following command in the Windows command line window:
1. View All port usage

C: \>Netstat-ano

Protocol local address external address status PID

TCP 127.0.0.1: 1434 0.0.0.0: 0 listening 3236
TCP 127.0.0.1: 5679 0.0.0.0: 0 listening 4168
TCP 127.0.0.1: 7438 0.0.0.0: 0 listening 4168
TCP 127.0.0.1: 8015 0.0.0.0: 0 listening 1456
TCP 192.168.3.230: 139 0.0.0.0: 0 listening 4

TCP 192.168.3.230: 2929 117.79.91.18: 80 established 4732
TCP 192.168.3.230: 2930 117.79.91.18: 80 established 4732
TCP 192.168.3.230: 2931 117.79.91.18: 80 established 4732

2. view the usage of the specified port
C: \>Netstat-Aon | findstr" 9050"

Protocol local address external address status PID

TCP 127.0.0.1: 9050 0.0.0.0: 0 listening 2016

P: Have you seen it? The port is occupied by the process whose process number is 2016. Continue to execute the following command: (you can also view the PID process in the Task Manager)

3. view the PID Process
C:\>Tasklist | findstr" 2016"

Image name PID session name session # memory usage
========================================================== ==========
Tor.exe 2016 console 0 16,064 K
P: clearly, tor occupies your port.

4. End the process

C: \>Taskkill/F/T/IM tor.exe

Note: If you do not like commands, you can also use the TCP View tool for operations, which is faster and more convenient.
