grazie mille x le risposte :-)
Listen 80 non l'ho trovato ho trovato questo:
# Port: The port to which the standalone server listens. Certain firewall
# products must be configured before Apache can listen to a specific port.
# Other running httpd servers will also interfere with this port. Disable
# all firewall, security, and other services if you encounter problems.
# To help diagnose problems use the Windows NT command NETSTAT -a

Port 80
ps dimenticavo, durante la ricerca ho trovato 2 file httpd.conf uno dentro C:\Programmi\EasyPHP1-8\apache\conf e il secondo dentro C:\Programmi\EasyPHP1-8\conf_files devo modificarli tutti e 2? immagino di si :-)
