On my windows 10 machine, any time I try to access HTTP port 80, it is in use and cannot be bound to. I understand this is being used by the IIS that comes with Windows 10. However, I don't have a single web server configured. This is what my IIS Manager looks like: Windows 10 IIS Manager

Despite not having any sites at all, when I navigate to http://localhost, I see: Windows 10 IIS locahost not found

In my Windows Services, there is no WAS or W3SVC.

In my experience, this means there is some process somewhere bound to this port that I can probably terminate, kill, and completely stop totally.

How do I do this? I'd like other things that are not this to bind to port 80.

  • I assume if you look at the System process in Process Explorer (TCP/IP tab of the process properties) it is listening on port 80. If you run net stop http it stops listening. – HelpingHand Sep 27 '18 at 17:39
  • I am cautious of this because when I run net stop http, I am told that two services are dependent on them; namely SSDP Discovery and Print Spooler. Though I don't know much about the former, I would hate to shut off the latter for fear that I will no longer be able to print. I guess if there is no other way... – Michael Plautz Sep 27 '18 at 18:50

    If you are not using IIS, just uninstall it in "Turn Windows features on or off". This won't break anything. – harrymc Sep 27 '18 at 19:15
  • @harrymc - I did just this, and after turning off "Internet Information Services" (and restarting, which is required) there is still a service listening on port 80 generating the page above. This is bizarre. – Michael Plautz Nov 7 '18 at 15:08
  • Please run in cmd the command netsh http show iplisten. See also if netsh http show urlacl shows anything starting with http://+:80. – harrymc Nov 7 '18 at 16:20
