System using port 80 since upgrade to windows 10 [closed]

Question

Ever since I have upgraded to windows 10, port 80 has been in use by the system. Is there anyway that I can stop the system from using port 80? Or can I change the port that apache uses?

Thanks

Edit: The process that is using port 80 is PID: 4

Answer 1

I had the same problem after upgrading to Windows 10, and for me, the culprit was the IIS service: "World Wide Web Publishing Service". After stopping/disabling it, it freed up port 80.
