Oh first of all make sure your apache server is running by going to "Apache HTTP Server 2.2" in your start menu and click "Monitor Apache Servers".
If you already have an icon in your task bar then you wont need to do this.
On the icon make sure theres a Green Arrow saying "Running 1 of 1 apache servers." If not click on it and click start servers.

1. Go to "C:\Program Files\Apache Software Foundation\Apache2.2" and then go into htdocs. Now in here you can insert a file. HTML or PHP what ever.
