Windows Server containers

Microsoft Windows Server containers

As part of servicing each month, we publish updated Windows Server Base OS container images. With these updates, you can automate building updated container images or manually update them by pulling the latest version. Windows Server containers do not have a servicing stack and do not support in place updates like Windows Server or Windows client. Therefore, every month we rebuild the Windows Server Base OS container images with the updates and publish the updated container images.

For more information on update best practices, please refer to Update Windows Server containers.

Note Because of a required change in how the Server Core container image is generated for Windows Server, version 1809, Windows 10, version 1809, and Windows Server 2019, there will not be a delta container image for the May 2020 release. Instead of the delta container image, the release for May 2020 will be a new full container image that will replace the original RTM container going forward. Future delta releases will use the May 2020 container as the new baseline.

Important The Server Core Container image download size is a one-time increase from 736MB (delta image) to 1.72GB (full image) which will increase the download time. Later releases will include smaller delta images.
