Apache Start Problem on Windows

I just installed the apache 2.2 http server and I get this error message whenever I hit start:

How do I solve this?

Kill whatever is bound to port 80 (might be IIS for example)

---

you might have IIS running. and it runs as a service and starts each time you start windows. open Run type this and press ENTER key: services.msc

the Services console will open. now look for IIS(internet information services) service and open its properties and change its start-up mode to Manual from the dropdownbox. plus stop the service to free the port number 80 for Apache to use.

take a look at this link: Starting and Stopping IIS

I hope this helps.
