Since there's no install, removing the program is as simple as deleting the files or directory you placed them in. The download comes as a ZIP file with no installer, and there are two executable files in the ZIP, which may be a tad confusing. We couldn't get the included Help file to load, but the program itself seemed quite stable. You can also save the entire list to a text file, and alter the speed at which the list refreshes. If there's a lot of activity on your system, you can filter the list. If a particular program-or perhaps malevolent bit of spyware-is streaming data from your system, you'll be able to see it, and, with the handy context menus, either close the connection or end the process.

The list auto-updates as connections are created or destroyed, so you can see your network activity in real-time. You get a list of the TCP/UDP connections on your system, and the ability to interact with specific connections or the process that created them. TCPView presents you with a very simple interface that is appropriate to its purpose and relatively easy to use. If something on your system is running amok, or you think you might have a spy in your midst, or you're simply curious (or obsessive) about the inner workings of your network, give this simple program a look.
