Check the program used by the port in Windows

When we start an application, we often find that the ports required by the system are occupied by other programs. How do we know who owns the ports we need is a headache for many people, next we will introduce a very simple method, hoping to be useful to everyone. If we need to determine who occupies our port 9050
1. Windows Platform
Run the following command in the windows command line window:

C:> netstat-aon | findstr "9050" TCP 127.0.0.1: 9050
0.0.0.0: 0 LISTENING 2016

As you can see, the port is occupied by a process with the process number 2016. Continue to execute the following command:

C:> tasklist | findstr "2016"
Tor.exe 2016 Console 0 16,064 K

You know, tor occupies your port.
