The playlist below is a three-part video series that takes a user through the process of using Azure Image Builder to create a custom Windows 10 multi-user image.  The first video starts with an overview and configuring a subscription for Azure Image Builder.  The second video demonstrates creating and deploying a template and building an image based on that template.  The third video walks through the steps to add software to the image in the build pipeline.

Azure Image Builder, now in Public Preview, is an Azure service that provides an imaging pipeline.  With Image Builder, you start by selecting a Windows or Linux source image from the Azure Marketplace, RHEL ISO, or existing custom image.  Then apply a list of customizations to modify the image, and specify an output location of a VHD, Managed Image, or Shared Image Gallery.  Once submitted to Azure Image Builder, the service builds and outputs the image.
