Apache Webserver

So, I ended up installing 2 apache webservers on my local machine. One is the wampapache server and the other is the regular outside guy, Apache 2.2. So whenever I start my machine, i would like for the wamp apache to pick up port 80 so that I can do my development, but sometimes the outsider Apache picks it up. And what is the best way to find who has picked it up?Follow this command on cmd:
"netstat -o -n -a PIPE findstr 0.0:80".
that gives you the process id that is occupying the local host. thats how I kill the processes I dont need. Another friendly tip for you :)
