apache - Xampp port 80 already use

Question

I have installed XAMPP on my pc and I change all port from '443' to '4433' and '80' to '8080' but when I start Apache it say me that port '80' is already use but Apache must use '8080' and when I go to 'http://localhost/' it display me a 404 error then I don't know what to do.

With netstat -ao on 'cmd' I see that port '80' is using by a program whit 'PID=4' and I see in the task manager that this PID is for "NT Kernel & System" so I can not kill it.

Answer 1

Please try with the port number http://localhost:8080 it seems like you have changed the port from here C:xamppapacheconfhttpd.conf

Listen 12.34.56.78:80 to 8080

Listen 80 to 8080 Alternative if want to use port 80 then If the skype is open try to change the port from the select options(80/443).Sometimes this is the problem.IIS server if running it might use the same port You can use some tools to kill the process for example, currports, TCPview etc.Hope it helps to solve your problem.
