Extended support is scheduled to end on January 9, 2029. As a Long-Term Servicing Channel (LTSC) release, 2019 receives cumulative updates that bundle quality and security improvements; following the end of mainstream support, these updates focus exclusively on monthly security releases. The IoT 2019 variant adheres to a separate but aligned lifecycle under the Fixed Lifecycle Policy, with mainstream support also concluding on January 9, 2024, and extended support ending on January 9, 2029. Microsoft recommends migration paths from Windows Server 2019 to or 2025 via in-place upgrades or clean installations to maintain access to ongoing support and features. After extended support ends in 2029, Extended Security Updates (ESU) may be available for continued security protection, similar to policies for prior versions.
