In this section, we’ll walk through the straightforward steps to check which ports are open on your Windows 10 machine. This will help you understand your network activity and troubleshoot any connectivity issues.

Step 1: Open Command Prompt

Press the Windows key, type "cmd" into the search bar, and hit Enter.

Step 4: Close Command Prompt

After reviewing, you can simply type exit and press Enter to close the Command Prompt.

Once you’ve gathered the necessary information, closing the Command Prompt will finalize your session. There’s no need to keep it open if you’re done checking ports.

After running these steps, you’ll have a better understanding of what your computer is communicating with over the network. You’ll be able to diagnose issues or confirm normal activity by seeing which ports are open or closed.
