I am running the latest Docker CE, 17.09, under Windows 10 Pro, and using two different examples am getting Permission denied.

Docker site example: docker run -d -p 80:80 --name webserver nginx

AWS site Docker example: docker run -p 80:80 hello-world

both returned the same error.

docker: Error response from daemon: driver failed programming external connectivity on endpoint XXXXX: Error starting userland proxy: Bind for 0.0.0.0:80: unexpected error Permission denied.

I solved my issue on Windows 10 Pro, turned out I had the World Wide Web Publishing Service turned on somehow. Took me a while to find that, after noting via netstat -a -n that I had a :80 listener somewhere/somehow. Silly me. Shut it down, and I was fine with port 80.
