Summary
Windows 11, versions 24H2, 25H2, and 26H2 share a common core operating system with an identical set of system files. Therefore, the new features in Windows 11, version 26H2 are included in the latest monthly quality update for Windows 11, versions 24H2 and 25H2 but are in an inactive and dormant state. These new features will remain dormant until they are turned on through the “enablement package,” a small, quick-to-install “master switch” that activates the Windows 11, version 26H2 features.
The enablement package is a great option for installing a scoped feature update like Windows 11, version 26H2 as it enables an update from version 24H2 or 25H2 to version 26H2 with a single restart, reducing update downtime. This enables devices to take advantage of new features now. For versions 24H2 or 25H2 devices that receive updates directly from Windows Update or Windows Server Updates Services (WSUS), devices automatically get the enablement package by installing the feature update to Windows 11, version 26H2.
