IIRC, Windows containers require that the container be built with a base image that matches the host for it to work at all (like, the exact build of Windows has to match). Guessing that’s how they get a ‘stable ABI’.

…actually, looks like it’s a bit looser these days. Version matrix incoming: https://learn.microsoft.com/en-us/virtualization/windowscont...

The ABI was stabilised for backwards compatibility since Windows Server 2022, but is not stable for earlier releases.
