Windows Server 2022 has transitioned from mainstream support into extended support, giving administrators several more years of security coverage and a clear runway to plan their next move. Monthly security patches remain free through October 14, 2031, while hotpatching has been extended for a subset of deployments.
The shift took effect on October 13, 2026, when the October 2026 security update shipped as the final mainstream support release for the product. From that point forward, Windows Server 2022 follows the standard Long-Term Servicing Channel (LTSC) timeline that Microsoft set when it first unveiled the release.
What changes when mainstream support ends
Extended support keeps the platform protected but narrows what Microsoft ships each month. Going forward, customers receive security updates at no additional cost, while non-security fixes and new features are no longer part of the regular monthly cadence.
The October 2026 security update was the last mainstream support update available for this version, according to Microsoft’s lifecycle notice. After that, only the security stream continues until the extended support cutoff.
How long Windows Server 2022 will keep receiving security updates
Microsoft first introduced Windows Server 2022 in March 2021 and made it generally available in September 2021 as a ten-year LTSC release. The remaining support window breaks down as follows:
- Monthly security updates: continue at no additional cost through October 14, 2031.
- Hotpatching: extended until October 2027 for systems on the Datacenter: Azure Edition, one year past the mainstream end date.
The hotpatch extension matters for Azure Edition customers because hotpatches let administrators apply security fixes without restarting, which keeps workloads online during patching windows.
The recommended upgrade target: Windows Server 2025
Microsoft’s guidance to IT administrators is to plan a move to Windows Server 2025, the latest release in the LTSC line. Windows Server 2025 began rolling out to Windows Insiders in January 2024 and reached general availability in November 2024.
According to the company’s lifecycle platform, Windows Server 2025 will reach end of mainstream support in November 2029, followed by an additional five years of extended support until November 14, 2034. That timeline gives organizations that migrate a fresh mainstream support window of roughly three years, with security coverage stretching close to a decade from general availability.

Where to check exact servicing dates
Microsoft points administrators to the Windows Lifecycle FAQ page and the Lifecycle Policy search tool for precise dates on every supported release. These resources list the end of mainstream support and end of extended support milestones release by release, which is the cleanest source of truth when planning a migration calendar.
Other Windows lifecycle moves in the same window
The Server 2022 transition was one of several lifecycle announcements Microsoft made in mid-October 2026. On the same day, the company confirmed that devices running Windows 11 24H2 Home and Pro editions no longer receive security and non-security preview updates and advised customers to upgrade to Windows 11 26H2, the latest Windows 11 release also known as the Windows 11 2026 Update.
The week before, Microsoft also warned users to upgrade devices running unsupported versions of Windows, noting they will stop receiving security updates after the next year’s Windows Update certificate rotation. Planning both the server and client upgrades together can keep a fleet aligned on a single maintenance calendar.
What this means for IT planning
The takeaway is straightforward: existing Windows Server 2022 deployments remain safe to run while security updates ship, and there is no cost penalty for staying on the platform until October 2031. The mainstream support end, however, signals that any organization still relying on non-security fixes, new features, or out-of-band hotpatching outside Azure Edition should treat the next twelve months as the practical window to move production workloads to Windows Server 2025.
