TCPView Sysinternals
winget install --id=Microsoft.Sysinternals.TCPView -e
TCPView is a Windows program that will show you detailed listings of all TCP and UDP endpoints on your system, including the local and remote addresses and state of TCP connections. TCPView also reports the name of the process that owns the endpoint. TCPView provides a more informative and conveniently presented subset of the Netstat program that ships with Windows. The TCPView download includes Tcpvcon, a command-line version with the same functionality. When you start TCPView it will enumerate all active TCP and UDP endpoints, resolving all IP addresses to their domain name versions. You can use a toolbar button or menu item to toggle the display of resolved names. TCPView shows the name of the process that owns each endpoint, including the service name (if any). By default, TCPView updates every second, but you can use the Options|Refresh Rate menu item to change the rate. Endpoints that change state from one update to the next are highlighted in yellow; those that are deleted are shown in red, and new endpoints are shown in green. You can close established TCP/IP connections (those labeled with a state of ESTABLISHED) by selecting File|Close Connections, or by right-clicking on a connection and choosing Close Connections from the resulting context menu. You can save TCPView's output window to a file using the Save menu item.
TCPView is a Windows utility designed to display detailed information about all TCP and UDP endpoints on your system, including local and remote addresses, port numbers, connection states, and the associated process names. This tool provides a comprehensive view of network activity, making it easier to monitor and troubleshoot connections.
Key Features:
- Real-Time Monitoring: Displays active TCP and UDP endpoints with details such as connection states (e.g., ESTABLISHED, LISTENING) and remote addresses.
- Process Identification: Shows the name of the process or service owning each endpoint, aiding in identifying which applications are using network resources.
- Connection State Visualization: Highlights changes in connection states, new connections, and closed endpoints with color-coded indicators (yellow for changes, red for deletions, green for new connections).
- Command-Line Tool: Includes Tcpvcon, a command-line version that allows saving output as CSV or text files for further analysis.
