Roles, Role Services, and Features not in Server Core containers - Windows Server, version 1803

Applies to: Windows Server 2022, Windows Server 2019, Windows Server, version 1803

In Windows Server, version 1803, we've reduced the overall size of the Server Core container image to 1.58 GB. The way we've done this is by optimizing the architecture and removing things you don't need in a Server Core container. Some were things that didn't work in containers, some were roles and features no one's been using.

Important

We removed these from the Server Core container image, not Server Core itself.

Here's the complete list of features and roles removed from the Server Core container image:
