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 A
I had same problem.
Then when you use xampp control panel, sometime you have to face same problem as I was.
Go to xampp control panel. Using config button open configuration of control pannel. Then click service and port setting and under appache setting you can change your main port 80 to 8080.
Please try with the port number http://localhost:8080 it seems like you have changed the port from here C:\xampp\apache\conf\httpd.conf
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.
I had the same problem after upgrading to Windows 10. I had to stop the IIS service: "World Wide Web Publishing Service". After stopping/disabling it, it freed up port 80. Press Ctrl+Shift+Esc (opens taskmanager), Services and stop W3SVC service - World Wide Web Publishing Service;
