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 21H1 as it enables an update from version 2004 or 20H2 to version 21H1 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 21H1 features. Therefore, the new features in Windows 10, version 21H1 are included in the latest monthly quality update for Windows 10, version 2004 and Windows 10, version 20H2, but are in an inactive and dormant state. Windows 10, versions 2004, 20H2, and 21H1 share a common core operating system with an identical set of system files.
