Microsoft confirms Windows 11 26H2, urges IT admins to prepare for release

Windows 11 typically follows an annual update cycle, but Microsoft recently broke that tradition a bit by releasing a "26H1" version in the first half of this year as a "scoped" build for select new silicon PCs only. This version was not available for customers using 24H2 and 25H2 builds, as Microsoft is busy preparing version 26H2 for them, confirmed officially for the first time.

In a Windows IT Pro blog, Microsoft has urged IT admins to prepare for the upcoming release of Windows 11 version 26H2. The company has confirmed that this will be a small enablement package (eKB) that will simply light up certain disabled features that are already present in the operating system's code base. This means that the "refined" Windows update and deployment experience will be simpler and quicker, with minimal disruptions, as the feature update will simply toggle a few flags rather than performing a complete replacement.

Microsoft has explained that this is all possible because the standard Windows 11 releases share the same servicing branch and hence, the same source code. However, this also means that Windows 11 26H1 users won't be able to upgrade to 26H2 as that is a different branch, but this is something we have known for a while now.

Similar to previous annual feature updates, Windows 11 26H2 will offer the following support cycles:

• 24 months of support for Home, Pro, Pro EDU, and Pro for Workstations editions
• 36 months of support for Enterprise, Education, IoT Enterprise, and Enterprise Multi-session editions

Microsoft has not confirmed a concrete release date for Windows 11 26H2, but noted that it is "coming soon". If we go by the ongoing release cadence, we can expect it to begin rolling out in early October 2026.

As such, IT admins have been encouraged to begin validating Windows Insider releases in the Experimental Channel, plan rollout rings, and strategize the utilization of their existing deployment tools.
