Windows Server 2022 support moved into its extended phase on October 13, 2026, marking the end of mainstream support. However, Microsoft will continue providing monthly security updates until October 14, 2031.
The October 2026 security update was the final release under mainstream support. Consequently, organizations now enter the next stage of the operating system’s lifecycle, rather than losing security coverage immediately.
Microsoft introduced Windows Server 2022 in March 2021 and made it generally available that September. As a Long-Term Servicing Channel release, it came with a ten-year support lifecycle.
Monthly Security Updates Continue Until 2031
The transition means Windows Server 2022 support will continue for another five years through the extended support programme.
Microsoft says this phase includes monthly security updates at no additional cost. Therefore, administrators can continue receiving security fixes while preparing their longer-term migration plans.
The distinction between mainstream and extended support matters for organizations managing upgrade schedules. Although mainstream support has ended, the October milestone does not leave existing installations without monthly security patches.
Nevertheless, administrators should account for the final October 2031 deadline when planning infrastructure changes.
Azure Edition Hotpatching Gets Another Year
Separately, Microsoft has extended hotpatching availability for Windows Server 2022 Datacenter: Azure Edition until October 2027.
That extension runs for one year beyond the end of mainstream support. However, it applies specifically to the Azure Edition, rather than every Windows Server 2022 installation.
Organizations using that edition therefore have a separate hotpatching deadline to consider alongside the broader security update schedule.
Microsoft Encourages Windows Server 2025 Migration
Meanwhile, Microsoft recommends that administrators plan an upgrade to Windows Server 2025 to regain full mainstream support.
The newer release reached general availability in November 2024, following its introduction to Windows Insiders earlier that year.
According to Microsoft’s lifecycle schedule, mainstream support for Windows Server 2025 ends in November 2029. Extended support then continues until November 14, 2034.
As a result, upgrading provides a longer overall support period, alongside access to the newer release’s mainstream support phase.
A Free Trial Supports Upgrade Planning
For organizations evaluating a migration, Microsoft offers a free 180-day Windows Server 2025 trial through its Evaluation Center.
Administrators can use that evaluation period to assess the release before committing to deployment.
For now, the immediate change concerns the support phase rather than the end of security updates. However, organizations should distinguish between the October 2027 hotpatching deadline for Azure Edition and the October 2031 security support deadline.
