PortExpert is a free system process port monitoring and management tool, developed by KC Softwares from France. Its purpose is simply to monitor any programs connected to the Internet in real time, letting you know which ports and what IP addresses they are connected to. It is essentially equivalent to dynamically executing the "netstat /ano" command in the CMD.
