How to Check if a Port is Open on Windows 10: A Step-by-Step Guide

Checking if a port is open on Windows 10 is a straightforward process, even if you’re not a tech wizard. All you need is the Command Prompt and a few simple commands. First, open the Command Prompt as an administrator. Then, type in “netstat” along with the specific parameters to see the status of all your ports. If you’re looking for a particular port, you can use the “findstr” command to narrow it down. That’s it! By following these steps, you can easily determine if a port is open on your Windows 10 computer.

How to Check if Port is Open on Windows 10

Knowing if a port is open on your Windows 10 machine can help with troubleshooting network issues or setting up a server. Follow these steps to find out quickly and easily.

Step 1: Open Command Prompt

To start, open the Command Prompt with administrative privileges.

Right-click the Start button and select “Command Prompt (Admin)” or “Windows PowerShell (Admin).” This ensures you have the necessary permissions to run commands that interact with your network settings.

Step 2: Type the netstat Command

Next, type netstat -a and hit Enter to display all active connections and listening ports.

The netstat command lists all current network connections and listening ports. The -a parameter shows all active connections, which helps identify open ports.

Step 3: Use the findstr Command

If you’re looking for a specific port, type netstat -a | findstr :[port number] and press Enter.

The findstr command acts like a filter, helping you sift through the list of active ports to pinpoint the one you need. Replace [port number] with the port you’re checking.

Step 4: Analyze the Output

Review the output to see if the desired port is listed as “LISTENING.”

The output will display a list of active ports. If your port shows up with the status “LISTENING,” it’s open and ready for connections.

Step 5: Close Command Prompt

Once you’re finished, type exit and press Enter to close the Command Prompt.

Closing the Command Prompt ensures no unauthorized commands can be entered, keeping your system secure.

After completing these steps, you’ll know if the port you’re checking is open and listening for connections on your Windows 10 computer.

Tips for Checking if Port is Open on Windows 10
