How does Windows know how to resolve mDNS queries?

When you install Bonjour for Windows you can resolve any ".local" mDNS name from anywhere in the system.

For example, you can "ping some_computer.local" and mDNSResponder.exe (Bonjour/mDNS Daemon) will respond.

However, mDNS operates on port 5353 so how does Windows know how to resolve these DNS queries?

Is mDNSResponder.exe hooking into the Windows DNS Resolver somehow?
