Microsoft has issued a reminder that Windows Server 2022 will reach the end of mainstream support on October 13, 2026. The October 2026 security update will be the last release issued under mainstream support for this version.
What changes for admins
After that date, Windows Server 2022 moves into extended support, during which it will continue to receive monthly security updates at no additional cost through October 14, 2031. Non-security fixes and new feature updates, however, will no longer be provided once mainstream support ends.
Microsoft also confirmed that hotpatching for Windows Server 2022 has been extended until October 2027, one year beyond the mainstream end date, but only for systems running the Datacenter: Azure Edition.
Windows Server 2022 originally launched as a Long-Term Servicing Channel (LTSC) release in September 2021, carrying a total support lifecycle of 10 years.
Upgrade path: Windows Server 2025
Microsoft is urging organizations to begin planning migrations to Windows Server 2025, the current LTSC release, which reached general availability in November 2024. That version will receive mainstream support until November 13, 2029, followed by extended support through November 14, 2034.
The company recommends admins evaluate upgrade options and start deployment testing early to ensure a smooth transition. A free 180-day trial of Windows Server 2025 is available through the Microsoft Evaluation Center for organizations that want to validate compatibility before committing to a full rollout.
Why it matters
While extended support keeps security patches flowing for another five years, organizations still running Windows Server 2022 should treat this as a planning trigger. Feature updates and non-security fixes end this cycle, and enterprises with long procurement and testing timelines should begin evaluating Windows Server 2025 now to avoid being caught unprepared as the 2031 extended support deadline approaches.
