Summary
Azure Stack HCI, versions 21H2 and 22H2 share a common core operating system with an identical set of system files. Therefore, the new features in Azure Stack HCI, version 22H2 are included in the latest monthly quality update for Azure Stack HCI, version 21H2, 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 Azure Stack HCI, version 22H2 features.
The enablement package is a great option for installing a scoped feature update like Azure Stack HCI, version 22H2 as it enables an update from version 21H2 to version 22H2 with a single restart, reducing update downtime. This enables devices to take advantage of new features now. For version 21H2 devices that receive updates directly from Windows Update, devices automatically get the enablement package by installing the feature update to Azure Stack HCI, version 22H2.
Important To update a device that is running Azure Stack HCI, version 20H2, you must first update to Azure Stack HCI, version 21H2. Then you can update to Azure Stack HCI, version 22H2 by using this feature update enablement package.
