Windows Server build 18312 is a build of Windows Server, version 1903. It was only released as a Docker image.

Container image[edit source]

This build was only officially released in the form of a Docker layer image file and has been optimized for use in a container. By default, it does not spawn an interactive session on boot, the Administrator account is password-protected and networking services are disabled compared to regular desktop builds.

In order to use this build in ordinary virtual machine solutions, it is required to convert the layer image to WIM format and then install the build by manually using dism.exe and bcdboot.exe. Before booting into the build, the number of initial sessions also has to be increased, otherwise the system will be seemingly stuck on the boot screen:[note 1]

[HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Session Manager]
"NumberOfInitialSessions"=dword:00000002

Notes[edit source]

  1. This is not required for Hyper-V enhanced sessions, which use Remote Desktop Protocol to control the virtual machine.
