View port usage in windows

In windows, check the port usage and start running. Enter the command prompt "cmd" and enter "netstat-ano" to view all connected PIDs. Then, find the program corresponding to the PID in the task manager. no PID, you can select "View"-" www." www.2cto.com in the task manager. when starting the application, we find that the ports required by the system are occupied by other programs, how to know who owns the port we need is a headache for many people. The following describes a very simple method, I hope it will be useful to everyone. If we need to determine who is occupying port 9050, and the Windows platform will execute: C in the windows command line window: \> netstat-aon | findstr "9050" TCP 127.0.0.1: 9050 0.0.0.0: 0 LISTENING 2016 www.2cto.com? The port is occupied by processes with process number 2016. continue to run the following command: C: \> tasklist | findstr "2016" tor.exe 2016 Console 0 16,064 K
It is clear that the tor occupies your port.
