The operating system of the container does not match

I have created a Windows Server 2016 VM, build 15063.2.

I installed Docker EE according to these instructions.

I can pull images and list them. But I cannot run them.

I tried running microsoft/windowsservercore using this command.

docker run -it microsoft/windowsservercore cmd

It fails saying the version of the OS doesn't match. Full error output is below.

docker: Error response from daemon: container 266a8f9f77f7ee57efb41ecd74001721b57fbbf1fc85150fd5156627782b6f61 encountered an error during CreateContainer: failure in a Windows system call: The operating system of the container does not match the operating system of the host.

How do I figure the correct version of the host OS to use?
