Method/Step

Step 1: Start---->Run---->cmd, or use the window R key combination to bring up the command window

Step 2: Enter the command: netstat -ano to list the status of all ports. In the list, we observe the occupied port, such as 49157, and find it first.

(For the website, the network apatch server is the default 80, the database mysql is 3306)

Step 3: Check the PID corresponding to the occupied port, enter the command: netstat -aon|findstr "49157", press Enter, write down the last digit, which is PID, here is 2720

Step 4: There are two methods

1. Continue to enter tasklist|findstr "2720" , press Enter, check which process or program occupies port 2720, the result is: svchost.exe

2, or we open the task manager, switch to the process tab, and check the PID column corresponding to 2720 Who is the process? If you cannot see the PID column, as shown below:

Then we click [View]--->[Select Column], check the box in front of PID (Process Identifier), and click Sure.

In this way, we can see the PID column and see who the process corresponding to 2720 is. If not, we can check the box in front of the display process of all users below, and then we can see it. The image name is The description of svchost.exe is that it is the main process of Windows, which is exactly the same as what is viewed by the above command.
