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 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;
