What is the current state of mDNS on Windows?

Question

It used to be that Windows would only resolve multicast DNS addresses (say, example.local ) if iTunes was installed. Is that still true or has that changed in recent Windows versions? (I gave up on Windows years ago and so I cannot check easily myself.)

Answer 1

DNS-SD and mDNS are available in a new extension to Windows.Devices.Enumeration in Windows 10.

(Side note to these slides: The watcher.Updated event handler should be set in order for watcher.Added to trigger.)

Answer 2

The latest Windows 10 Insider build has mDNS firewall rules and have added mDNS and DNS-SD code all over the core libraries in Windows. So the state will probably turn into full support in a future Windows update.
