Windows Server Support Timeline

Windows Server 2022, the latest Long-Term Servicing Channel (LTSC) version of Windows Server, was released in Aug. 2021. LTSC versions of Windows Server provide five years of Mainstream support and five years of Extended support. Windows Server 2019, released in Nov. 2018, and Windows Server 2016, released in Oct. 2016, are also supported on the LTSC. Windows Server 2022, 2019, and 2016 offer Desktop Experience (“Full”) and Server Core installation modes, with Server Core as the default installation mode.

​Windows Server 20H2, released in Oct. 2020, is the last version of Windows Server available through the Semi-Annual Channel (SAC) and will leave support in Aug. 2022, a three-month extension from the original end of support date. Future versions of Windows Server will be available only through the LTSC, and organizations using versions of Windows Server released on the SAC should migrate to LTSC versions of Windows Server. Updated container base OS images of Windows Server (not shown), including Server Core and Nano Server configurations, will continue to be made available two to three times annually.
