问题
Does Windows (some modern flavour) have an mDNS server installed and/or running by default? If so then how does one tell it, preferably dynamically, to start/stop advertising a new service?
If there is no standard then how does one deal with the problem of conflicts trying to run multiple mDNS servers in that environment?
Basically, I want to implement a service that will run on Linux, Windows and Mac OS X and which needs to advertise its zeroconf webserver location using mDNS. On Linux I just use avahi-publish (or install a config file). I'm guessing that the answer will be straightforward for OS X. I'm struggling to find information for Windows.

No, Microsoft doesn't directly support Multicast-DNS.
However, there appear to be several 3rd-party alternatives:

Starting with Windows 10, Microsoft seems to make strides towards a native Windows implementation of mDNS and dns-sd.
Their first iteration resulted in mDNS network flooding:
Windows 10, in its default configuration, will spam its local networks by responding to all mDNS requests with null response packets.
And following up:
This issue was fixed in Windows 10 1511 (10586) and above
Recent builds have seen improvements all over the place and Windows now offers a dns-sd service discovery library which is currently limited to UWP apps.

Last time I needed one, Apple's Bonjour Print Services for Windows was the most convenient mDNS client for Windows I could find. Only 5MB.

Windows 10 supports natively mDNS/Zeroconf, but only for modern APIs, not for Win32 applications. If you have such an application, a third party service is required.

Have also successfully used C++/WinRT for dnssd discovery directly from C++ now. It appears from our perspective to be quicker and more reliable to query services and will let you easily install a watcher to get notifications when devices arrive etc. Of course, this is limited to versions of Windows 10 with support for C++/WinRT, which starts with 10.0.17134.0 (Windows 10, version 1803).
One caveat: We've noticed that it does not provide, nor recognise, a FQDN (trailing dot). So for a device that Bonjour OR Avahi would give an address of mydevice.local., Windows instead gives mydevice.local. Attempting to ping mydevice.local. under Windows 10 (1809) fails.

The short answer is to support both Avahi and Bonjour. You'll need Bonjour support to run on OSX anyway, and if a Windows user has installed iTunes they'll already be running it.
As a fallback for Windows users not running iTunes, you can compile Avahi as a library for Windows (with a bit of effort) and bundle it. This is a non-trivial bit of packaging, but the alternative is requiring your Windows users to install iTunes in order to use your application.
