Windows 11 support dates (November 2026): 24H2 Home/Pro already ended, 23H2 Enterprise/Education ends November 10

This article restates the official servicing table and the 24H2 status notice. It is not a security advisory for a specific CVE, and upgrade availability still depends on hardware eligibility and rollout.

From Microsoft’s Windows 11 — release information table (ISO dates; consulted November 5, 2026):

26H1 is scoped to certain new devices from early 2026. Microsoft states it is not offered as an in-place feature update from 24H2 or 25H2 on existing devices.

Microsoft’s 24H2 status page (current status as of October 28, 2026) states that as of October 13, 2026, Windows 11 version 24H2 Home and Pro editions have reached end of updates. Those devices no longer receive monthly security and non-security preview updates. Microsoft recommends updating to Windows 11 version 26H2 or 25H2.

24H2 Enterprise and Education remain supported for monthly security updates until October 12, 2027. The September 22, 2026 non-security preview was described as the final non-security preview for those editions.

On the release-information table, 23H2 Enterprise, Education, IoT Enterprise, and Enterprise multi-session editions list end of updates on 2026-11-10. After that date those editions leave the supported servicing window listed by Microsoft. Organizations still on 23H2 should plan a move to a supported version (typically 25H2 or 26H2 when offered) before or as that date passes.

Per the 24H2 status notice, the 26H2 phased rollout has reached full availability for devices running 25H2 and 24H2:

If the feature update is not offered, eligibility, storage, drivers, or organization policy may block it. TricknFix’s community topic on 26H2 not appearing in Windows Update covers troubleshooting separately from this lifecycle summary.
