I tried pulling the windows/nanoserver image.
After that failed I looked around and found this site
Every one of them fails with the same error message
#docker pull mcr.microsoft.com/windows/nanoserver:1909 ltsc2019: Pulling from windows/servercore no matching manifest for unknown in the manifest list entries
