According to Microsoft’s official support documentation, Windows Server 2022 will exit mainstream support in October 2026 and transition into extended support. The operating system, released in March 2021, follows the Long-Term Servicing Channel (LTSC) model. Releases under this channel typically receive five years of mainstream support followed by five years of extended security updates, totaling ten years of security coverage.
No New Features After Mainstream Support Ends
Once Windows Server 2022 exits mainstream support in October, it will automatically transition into extended support. During this phase, Microsoft will continue delivering necessary monthly security updates to patch vulnerabilities, meaning enterprises currently running this version have no urgent need to rush an upgrade. However, following standard practice, Microsoft will no longer deliver feature updates once mainstream support ends – extended security updates cover essential security patches only, nothing more.
Windows Server 2022 launched in March 2021, with mainstream support concluding in October 2026 and extended support running through October 14, 2031. Before extended support expires, IT administrators can continue installing and deploying necessary security updates through the normal update process.
Microsoft Recommends Upgrading to Windows Server 2025
Windows Server 2022 was built on the Windows 10 codebase. Microsoft has since released Windows Server 2025, developed on the Windows 11 codebase. Windows Server 2025 now supports lossless in-place upgrades, meaning enterprises can migrate directly from an older version to Windows Server 2025 without reinstalling the operating system from scratch.
Microsoft is actively recommending that enterprises upgrade to Windows Server 2025, citing the new version’s expanded feature set and advantages in AI-driven management capabilities. Microsoft advises IT administrators to begin evaluating Windows Server 2025 early to complete migration well ahead of any deadline. It is worth noting that upgrading to Windows Server 2025 is not free – enterprises must purchase a license to use it, as server editions have never supported free upgrades and each version requires its own licensing.
