Microsoft has introduced a "26H1" version of Windows 11, which is a scoped build for select new silicon PCs and not accessible to users on the 24H2 and 25H2 builds. The company is preparing for the release of version 26H2, which will be delivered as a small enablement package (eKB) to activate features already in the operating system's code. Users of Windows 11 26H1 will not be able to upgrade to 26H2 as they operate on different branches. Windows 11 26H2 will have a support cycle of 24 months for Home, Pro, Pro EDU, and Pro for Workstations editions, and 36 months for Enterprise, Education, IoT Enterprise, and Enterprise Multi-session editions. A specific release date for Windows 11 26H2 has not been announced, but it is expected to roll out soon, potentially in early October 2026. IT administrators are advised to validate Windows Insider releases and prepare rollout strategies.
