System Process is listening on port 80 (Vista)

I have just noticed that port 80 is in use by the System Process.  I have not noticed this before and I am wondering if something has gone "astray".

How do I determine what is causing the System process to bind to port 80.  I do not have IIS running (According to Control Panel->Windows Features).

An output from the HTTP server is below.
Trying 192.168.1.64, 80 ... Open
