Windows 10 – Binds to privileged non-admin ports, win-10 / server-2016

Is not there a concept of privileged ports in newer versions of Windows? I was able to bind to any privileged port of an unmanaged user. Is that normal?

Below are the steps I followed:

  1. Logged in as non-administrator in Windows Server 2016.
  2. Installed Python
  3. Start the server via port 80 Python -m
    SimpleHTTPServer 80
  4. Another user on the same system could do this
    Access via http: // localhost,

I got the impression that administrator privileges are needed to connect to privileged ports. Any comments?
