Windows containers have two execution models.

In one, each container gets its own kernel copy, while the other one works like Linux containers, and indeed you need a recent version, as there were some issues doing that on older versions, which is yet another reason to be running Windows 11.

Note that having kernel copy to go along the containers is also existing on Linux world, this is what advanced security models like Kata containers.

There is plenty of Windows software on big corporations that will never be ported to Linux, and that is the golden use case for at least put them into containers.

One such example are all the .NET Framework applications that will never be rewritten into modern .NET, or Windows Services (aka UNIX daemons).
