Microsoft has issued a reminder to system administrators that mainstream support for Windows Server 2022 is coming to an end very soon. In less than two months, the operating system will switch to extended support mode.
What this means in practice is that only security updates will be available from October 13, 2026 to October 14, 2031. Microsoft would prefer that anyone still using Windows Server 2022 upgrade to Windows Server 2025, however.
In a message posted to the Windows Message Center in recent days, Microsoft says:
On October 13, 2026, Windows Server 2022 will reach end of mainstream support. The October 2026 security update will be the last mainstream support update available for this version. After this date, Windows Server 2022 will transition to extended support, which includes security updates at no additional cost, and will continue to receive monthly security updates through October 14, 2031. For more information, see the Fixed Lifecycle Policy.
Windows Server 2025 is now the latest Long-Term Servicing Channel (LTSC) release for Windows Server. To help keep your environment protected and supported, plan to upgrade to Windows Server 2025 for full mainstream support.

The company adds that more detailed lifecycle dates are availbale on the Windows Server 2022 lifecycle page. It adds: “For servicing timelines and related resources, see Windows Server release information, Lifecycle FAQ – Windows Server, and Microsoft Lifecycle Policy search tool”.
