Microsoft to End Mainstream Support for Windows Server 2022 in 2026, Extended Support to 2031
Microsoft has announced that Windows Server 2022, a long-term servicing channel release launched in March 2021, will exit mainstream support in October 2026 and automatically transition to extended support. During extended support, which runs until October 14, 2031, Microsoft will continue monthly security updates but stop feature updates. The company also noted that Windows Server 2025, based on Windows 11, supports in-place upgrades from 2022, though a new license purchase is required.
Windows Server 2022, a long-term servicing channel release, was officially launched in March 2021. Such versions typically receive five years of mainstream support and five years of extended security update support, providing a combined ten years of security updates. According to the official announcement, this version will end its mainstream support phase in October 2026 and automatically transition to extended support.
After mainstream support ends, Microsoft will no longer provide feature updates, but will continue to release necessary security updates on a monthly basis to address vulnerabilities. Extended support will last until October 14, 2031, during which IT administrators can install and deploy security updates through the normal process. Windows Server 2022 is developed from the Windows 10 branch, while Windows Server 2025 is based on Windows 11 and supports in-place upgrades, allowing enterprises to upgrade without reinstalling the operating system. Upgrading to Windows Server 2025 requires the purchase of a license, as server versions do not support free upgrades.
