Windows Server 2019 build 17661 is a build of Windows Server 2019. This build was released as a Docker Hub container image. The full image was then uploaded to BetaWiki Discord on 17 November 2024.

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.
