Unable to download any image in Windows16 docker
You can't pull the hello-world image from docker hub because it's linux image. I used to see it before while playing with Docker Container on windows when trying to do the same thing.
If you want to get different image like IIS, just run command follow the instructions:
First:
Install-PackageProvider ContainerImage -Force
Then
Install-ContainerImage -Name WindowsServerCore
After that, restart your docker container with
Restart-Service docker
And you'll have the images of IIS on your machine. I've tried to get the images of windows as the way we do in Linux but it always throw error as you have, I guess that all images we have on hub now are for Linux only, so if you want to have particular things, you must build it by yourselves or using existed images for Windows on Docker hub (about 9 or 10 images as I remember).
This is probably because there's no hello-world image for Windows. You can try running docker run windowsservercore cmd /C hello world.
