TCPView

TCPView is a free application that shows you all open network connections on your computer. It offers more information than Netstat, which is part of the Windows operating system. TCPView will show you the name of the process that is connected to that connection, local and remote addresses, port numbers, and other information. You can also terminate the process or close the connection. TCPView is a useful tool for diagnosing network problems and for monitoring network activity.

Here are a few ways you can use TCPView:

- To diagnose network problems. If you are having problems connecting to the Internet or another network, you can use TCPView to view all open connections on your computer. This will help you identify the connection that may be causing the problem.

- To monitor network activity. If you want to monitor how your applications are using the network, you can use TCPView to view all open connections that are caused by those applications. This can help you identify applications that are using too much bandwidth or that may be vulnerable to attacks.

- To terminate processes that are using the network. If you want to terminate a process that is using the network, you can use TCPView to view all open connections that are caused by that process. You can then right-click on the connection and select "End Process."
