Microsoft: Windows Server 2022 reached end of mainstream support
BLUF
Windows Server 2022 is now in extended support, so organizations need to plan upgrades before the final support cutoff in 2031.
NEWS
Microsoft announced that Windows Server 2022 reached the end of mainstream support on October 15, 2026. The platform will remain in extended support until October 2031, continuing to receive security updates but no new features or non-security changes.
Why I Care
This matters because many enterprises still rely on Windows Server for critical applications, identity services, file sharing, and infrastructure workloads. While security updates continue during extended support, organizations risk accumulating technical debt and may face higher costs or compatibility issues if they delay upgrades.
Next Steps
IT teams should inventory Windows Server 2022 systems, identify dependencies, and create an upgrade or migration plan to a supported platform such as Windows Server 2025 or Azure. Application owners should test compatibility now, and security leaders should budget for extended support options if upgrades cannot be completed before October 2031.
