Windows Server, version 23H2 is the first release of the Windows Server Annual Channel for Containers,[1] which was released on 24 October 2023.[2] The newly established Annual Channel is designed to support fast, containerized workloads under a host operating system level. Unlike Long-Term Servicing Channel releases, Annual Channel releases are only available in the form of a Server Core install in a similar fashion to the ill-fated Semi-Annual Channel release, and cannot be upgraded to from an existing Windows Server 2022 installation.

Annual Channel releases typically come with 18 months of mainstream support plus an additional 6 months of extended support. It is commercially distributed to volume-licensed customers via the Microsoft Software Assurance program. Developers can obtain a Windows Server Annual Channel release for development and testing purposes through an applicable Visual Studio subscription.
