The Feature Update for Windows 10 version 2004 and above and Windows Server version 2004 and above.
Prior to being offered this update KB4579311 has to be installed. You also need to have the servicing stack updates so make sure all of the updates are installed.
Then after you reboot your machine Windows update will offer the feature update.
Windows 10, versions 2004 and 20H2 share a common core operating system with an identical set of system files. Therefore, the new features in Windows 10, version 20H2 are included in the latest monthly quality update for Windows 10, version 2004 (released October 13, 2020), 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 10, version 20H2 features.
The enablement package is a great option for installing a scoped feature update like Windows 10, version 20H2 as it enables an update from version 2004 to version 20H2 with a single restart, reducing update downtime. This enables devices to take advantage of new features now. For version 2004 devices that receive updates directly from Windows Update, devices automatically get the enablement package by installing the feature update to Windows 10, version 20H2.
If a device is updating from Windows 10, version 1909 or an earlier version, this feature update enablement package cannot be manually installed. Instead, it is bundled and automatically included with the feature update to Windows 10, version 20H2. Note the installation time is not reduced in this scenario.
Some older machines in the studio such as the Lenovo machines have device issues. Clean installs of Windows recognized the machine and hardware drivers are on windows update. The studio has a USB stick with the latest version of Windows for clean installs.
