Tell Apache to use a different port. The setting can be changed in the httpd.conf file. Check the Apache documentation for help. I am not sure why you think port 80 is being used by your system though, unless you already have another server running on that port?

Is something like IIS running?
What happens if you point your browser at localhost?

The default server type for a service listening on port 80 is a web server, and the most likely server to run by default on a Windows machine would be IIS, so that seemed like the most likely thing to check for.
You can check and see if IIS is installed using the instructions here: http://www.howtogeek.com/howto/windows-vis...-windows-vista/

You can also check for a server response by opening a telnet session to your machine IP on port 80 and entering a GET command like so,

Start > Run > CMD
telnet 127.0.0.1 80

If that opens up a blank command window, type in GET and see if you get a response. That should tell you if you have a web server running on your system.

This is a typical IIS response to a get command sent through telnet.
