Xampp

I'm using Xampp, but the httpd service doesn't start.
Apache Start.bat doesn't work and reports:

Only one usage of each socket address (protocol/network address/port) is normally permitted. : make_sock: could not bind to address 0.0.0.0:80.

In my case the problem is Skype that is using the port #80, so:

• Open Skype and go to Tools > Options >Advanced > Connection
• Uncheck "Use port 80 and 443 as alternatives for incoming connections" checkbox
• Enter a different port in the "use port ___ for the incoming connections" field (80 is the default, change it with another -unused- port)
• Restart Skype!
