Actually nothing, except you want to be the guy that confuses Twitter users by just posting images of "Windows 10 Enterprise Build 20308" without further information to be at least a bit interesting.
ARM32 Docker images would be interesting... at least Nano Server is available on ARM. These images have unattend.xml file on C:\Windows\Panther which sets the password and lots of other settings. Removing it should make image behave like a normal Windows image. I'm currently testing that.
those images will only run on Hyper-V, make sure you don't use VMware, VirtualBox or any other virtualization software.
How the boot process of ContainerOS works? I'm going to test it on Hyper-V, hopefully it boots. Edit: still freezes at dots. Spoiler: froze here
From my testing so far, it works almost flawlessly, but attempting to configure optional features through Control Panel or Settings fails, attempting to remove "capabilities" through DISM fails because it appears it gets a capabilities list from Windows Update (???), which fails since this build isn't on Windows Update (in any of the public channels at least...), however, enabling features works fine through DISM, and seemingly everything else besides that works fine too.
Does anyone have any links for builds 20313 and 20317? I have all of these builds save for those two.
