apache - WampServer : Your Port 80 is actually used by Microsoft-HTTPAPI/2.0

Question

I've uninstalled my WampServer 2.5 and installed version 3.0 But apache service isn't running and tray icon is orange... Clicking on test port 80 gave me the following cmd output :

***** Test which uses port 80 *****
===== Tested by command netstat filtered on port 80 =====
Test for TCP
Your port 80 is used by a processus with PID = 4
The processus of PID 4 is 'System' Session: Services
The service of PID 4 for 'System' is 'N/A'
*** ERROR *** This service IS NOT from Wampserver - Should be: 'wampapache'
Test for TCPv6

Your port 80 is actually used by :

Press Enter to exit...

ISS Service has been disabled before and the Activation Windows service process too by the wampserver forum.

What is the problem then ??

Update 2017- Wamp version 3.0.6

Right click on Wamp--> tool--> apache section-->use a port other than 80
