Base image servicing lifecycles
Applies to: Windows Server 2022, Windows Server 2019, Windows Server 2016
Microsoft has delayed the scheduled end of support and servicing dates for a number of products to help people and organizations focus their attention on retaining business continuity. See Lifecycle changes to end of support and servicing dates entry from April 14, 2020 for more information.
Windows container base images are based on either Long-Term Servicing Channel releases or Semi-Annual Channel releases of Windows Server. This article explains how long support will last for different versions of base images from both channels.
The Semi-Annual Channel is a twice-per-year feature update release with eighteen-month servicing timelines for each release. This lets customers take advantage of new operating system capabilities at a faster pace, both in applications (particularly those built on containers and microservices) and in the software-defined hybrid data center. For more information, see the Windows Server Semi-Annual Channel overview.
For Server Core images, customers can also use the Long-Term Servicing Channel that releases a new major version of Windows Server every two to three years. Long-Term Servicing Channel releases receive five years of mainstream support and five years of extended support. This channel works with systems that require a longer servicing option and functional stability.
The following table lists each type of base image, its servicing channel, and how long its support will last.
