Windows Server 2022 moves to extended support, what you need to do now

Enterprises that depend on Windows Server 2022 as the backbone of their on‑premises workloads should be aware that the product has left mainstream support. As of 13 October 2026 Microsoft stopped providing new features and non‑security fixes, and the operating system entered extended support, which will continue with free security updates until 14 October 2031.

What the support change means for your business

• Mainstream support ended, no more new functionality, no non‑security patches.
• Extended support continues, Microsoft will still publish monthly security updates at no extra charge, but you will not receive any new non‑security improvements.
• Hot‑patching for Datacenter: Azure Edition is extended, the hot‑patching capability for the Azure‑optimised edition will be available through 1 October 2027.

The practical impact is simple: if you keep running Windows Server 2022 you will stay protected against known vulnerabilities, but you will miss out on any future feature enhancements and you will have to plan a migration before the extended‑support window closes.

Why upgrade to Windows Server 2025 now

Microsoft recommends moving to Windows Server 2025, which entered general availability in November 2024. The newer version brings a refreshed security stack, support for newer hardware, and a longer lifecycle, mainstream support runs until November 2029 and extended support will last until 14 November 2034. Migrating early gives you a clear path to stay on a fully supported platform for the next decade.

Test Windows Server 2025 without cost

A 180‑day evaluation licence is available from the Microsoft Evaluation Centre. The trial lets you install the OS in a lab or a pilot environment, validate compatibility with your applications, and measure performance before committing to a licence purchase.

What happens to Windows 11 desktop users?

The same announcement notes that Windows 11 version 24H2 for Home and Pro editions will stop receiving security and non‑security preview updates in early 2027. Microsoft advises upgrading those devices to Windows 11 26H2, the 2026 Update, to keep receiving the full patch cadence.

Practical steps for IT teams

1. Take inventory, identify every server still running Windows Server 2022, noting whether it is the standard edition or the Datacenter: Azure Edition.
2. Confirm update cadence, verify that your patch management system receives the monthly security updates that Microsoft will continue to publish until October 2031.
3. Plan the migration, map out a rollout to Windows Server 2025, prioritising critical workloads and those that will benefit from new security features.
4. Run the free trial, use the 180‑day evaluation to test application compatibility and any custom scripts you rely on.
5. Update Windows 11 endpoints, schedule the upgrade from 24H2 to 26H2 for all desktop devices that are still on the older build.
6. Review hot‑patching needs, if you run the Azure Edition, note that hot‑patching support ends in October 2027 and plan a move to a newer version before that date.

By following this checklist you can keep your infrastructure secure, avoid surprise outages when extended support ends, and take advantage of the newer capabilities that Windows Server 2025 offers.
