Note the installation time is not reduced in this scenario. Instead, it is bundled and automatically included with the feature update to Windows 10, version 21H2. If a device is updating from Windows 10, version 1909 or an earlier version, this feature update enablement package cannot be manually installed. For version 2004, 20H2, and 21H1 devices that receive updates directly from Windows Update, devices automatically get the enablement package by installing the feature update to Windows 10, version 21H2. This enables devices to take advantage of new features now. The enablement package is a great option for installing a scoped feature update like Windows 10, version 21H2 as it enables an update from version 2004, or 20H2, or 21H1 to version 21H2 with a single restart, reducing update downtime. 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 10, version 21H2 features.

Therefore, the new features in Windows 10, version 21H2 are included in the latest monthly quality update for Windows 10, version 2004, 20H2, and 21H1, but are in an inactive and dormant state.

Windows 10, versions 2004, 20H2, 21H1, and 21H2 share a common core operating system with an identical set of system files.
