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. It is the last Windows Server release supported by AMD64 processors that do not have the instructions SSE4.2
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.
