The program starts to find that the port is occupied? Find out who it is in 3 steps!

After using the operating system of Windows 8 / 8.1 or above, although the problem of port occupancy has rarely occurred, it will not pop up like the Windows 7 era. The error message "XX port is already occupied and the program cannot start" .

But from time to time, the common ports that 80 and 8080 online games will inevitably use will still be preempted by some programs in the background. Coupled with the previous intrusion problems at ports 139, 135, and 445, it is still necessary to pay attention to it.

Want to know which network ports are currently in use in the system, open a command prompt to use

netstat -ano

Let's go for a wave and look at the detailed list.

Then I want to see what program occupies a specific port, and then use

netstat -aon | findstr "XXXXX"

The command can be queried, remember to replace XXXX with the port number, the editor checks 135, then the detailed format of the command is

netstat -aon | findstr "135"

Look at the last row of numbers is 628, remember this, this is the most important program identification, which is the PID code that I have told you before, use it to query under the detailed information in the task manager, check one quasi.

Well, it is svchost.exe which is using port 135, the main service process of Windows. It is not a strange virus or dangerous program. Just keep it.

If the friends have problems with the port occupation when using the computer, they can directly kill the running program in the task manager to ensure that the program we are about to use will not be emotional because of these small things, right?
