WAMP Server

I share my computer with my friend, he works in asp, and he as installed some soft wares, when I start wamp service and click localhost it is not opening from wamp www folder instead it opens localhost from "wwwroot" folder which is in "inetpub" folder.
If I have to work in wamp should I unstall other software?

try to change the port from 80 to 8080

Try to change the port from 80 to some other 8080 or so
