Windows 11 version 23H2 has officially reached the end of its support lifecycle across all editions. Microsoft has released its final security update for the Enterprise and Education versions, meaning businesses and schools still running this release will no longer receive monthly security fixes.
The November 2026 security update, KB5131087, marks the end of the road for these editions. Microsoft had already stopped supporting 23H2 Home and Pro last year, while commercial customers received an additional year of updates under the longer support schedule.
The difference comes down to Microsoft’s servicing policy. Consumer editions of Windows 11 generally receive two years of security updates, while Enterprise and Education editions are supported for three years. Version 23H2 first arrived in October 2023, so its commercial support period has now run its course.
Organizations that have not yet moved to a newer release should make upgrading a priority. Unlike Home and Pro users, who are typically offered upgrades through Windows Update, Enterprise and Education devices may require IT administrators to manage the transition.
Several newer Windows 11 releases remain supported, including versions 24H2, 25H2 and 26H1. The 24H2 release still has roughly a year of support remaining for Enterprise and Education customers. Microsoft expects version 26H2 to receive security updates through 2029 for commercial editions.
There are exceptions for specialized Long-Term Servicing Channel (LTSC) and IoT releases, which follow different support schedules. Standard Windows 11 installations, however, need to move to a supported version to continue receiving security protection and feature updates.
