It could be many things, most common ones are Skype or Teamviewer.

You must be registered for see links

For Teamviewer:
Options > Advanced > Network > TeamViewer DirectIn check
Check Opens a dialog where the availability of TeamViewer is checked. The DirectIn Ports 80 and 5938 do not have to be opened, however, TeamViewer uses these ports for establishing faster connections.

There should be a port check button when you open Xampp CP, click that and it will show you the process thats using port 80. Post that process.
