Windows Server 2004 with Containers not having the windows:2004 image

Our software still needs the full windows server image to provide all of our functions.

We could work with mcr.microsoft.com/windows:1809 very well.

But since 10th of October 2020 this will not be updated anymore.

So we try to use a newer full windows server image. We tried with 1909 or 2004.

The main problem is, that there is no host machine provided in Azure, which works without issues with this image. (https://github.com/microsoft/Windows-Containers/issues/73)

Furthermore we would need a host machine, which has this image (mcr.microsoft.com/windows:2004) on its disk already. Otherwise we have to download and extract the 13 GB image each time our virtual machine scaleset adds more machines.
