The list is dynamic and presents a real time picture i.e. Windows already includes the Netstat command line program (which is quite complex and can interrogate TCP/UDP endpoints) but TCPView provides a far more informative and easy to read subset of the same information.ĭownload TCPView from Microsoft’s Sysinternals website here in a zip file.Įxtract the zip file and run the Tcpview.exe program to begin – a list of TCP/UDP connections is displayed along with the Process Name, Bytes Received/Sent and Remote Address etc. Using this program you can identify a malicious process, find out more about unusual processes and temporarily stop unnecessary data heavy processes – especially important if your internet is slow or data-limited e.g. Whilst of particular interest to network managers and advanced techs, it can be used by anyone to detect unknown, untoward, misbehaving or data-intensive processes on a network. It can help identify which programs are connecting to the internet and how much data they have sent or received. TCPView is a free Microsoft utility to show detailed listings of your network connections.
