Devices operating on the Windows 11 24H2 Home and Pro editions have reached their end of support as of October 13, 2026, meaning they will no longer receive monthly security updates or non-security preview updates. In contrast, the Windows 11 24H2 Enterprise and Education editions will continue to receive mainstream support until October 12, 2027. Microsoft encourages users to transition to Windows 11 26H2, which will be supported until October 2029. The rollout of Windows 11 26H2 is phased and will expand over the next few months. Additionally, systems running Windows 11 23H2 Enterprise, Education, and IoT Enterprise editions will cease to receive security updates in 30 days after the end of support for Windows 11 23H2 Home and Pro editions in November 2025. Windows Server 2022 has also reached the end of its mainstream support but will remain under extended support until October 2031. Users are advised to upgrade unsupported versions of Windows to continue receiving security updates.
