Apache Friends Support Forum

So i wanted to launch a web server to test sql injections and stuff like that, but when i tried to start an Apache server i got an error saying "Port 80 is in use by "Unable to open process" with PID 4. When i look up PID 4 in the Resource Monitor, it turns out to be the system process. So i wouldnt shut it down. But what can i do so i can still start an apache server?
