Microsoft published a blog post on the official Windows Experience blog in which Windows Servicing and Delivery Director of Program Management John Cable explained how customers get the update.
The explanation suggests that system administrators may run a manual search for updates on devices so that the new version of Windows 10 is returned.
Beginning today, the November Update is available for customers seeking to install the latest release. If you are ready to install the update, open your Windows Update settings (Settings > Update & Security > Windows Update) and select Check for updates. Once the update appears, you can select Download and install now.
What Cable fails to mention is that there are prerequisites and that Windows 10 version 1909 may not be offered at first or at all when a manual update check is started on the system.
Cable does mention that “compatibility issues and a safeguard hold” may prevent the delivery of the update to systems.
If the update check is successful, the “feature update to Windows 10, version 1909” should be listed on the Windows Update page. If Windows 10 version 1903 is the installed version, it is listed separately on the page.
Admins need to activate the “download and install” button to install the new feature update for Windows 10 on the device.
Windows 10 version 1909 requires an update that unlocks the new feature update on the device. If the prerequisite is not installed, the feature update is not offered on the device even if there are not any compatibility issues.
Günter Born suggests that KB4517245 is the required update. I confirmed his observation on two test machines that received the update. If you list the installed updates, you find KB4517245 — Feature Update to Windows 10 Version 1909 via Enablement Package (KB4517245 ) listed.
Basically, what administrators need to do is install the available updates for Windows 10 version 1903 to receive the update offer to Windows 10 version 1909 afterwards.
The updating should be quick and similarly to the installation of cumulative updates for the operating system. A restart is required and administrators may verify the version by running winver from Start.
What about pre-Windows 10 version 1903 systems?
Home and Pro editions of Windows 10 version 1803 won’t be serviced anymore after November 12, 2019; these systems need to be updated. Windows 10 version 1809 is still supported for another six months but administrators may upgrade devices running this version of Windows 10 as well.
The path is not as straightforward as it is for Windows 10 version 1903. Systems that run older versions of Windows 10 will be offered a full feature update (via Windows Search) instead of just a cumulative update; this means that the updating will take longer and that there is more room for errors.
It seems likely that the update will be made available gradually to users; those who cannot wait may upgrade manually to the new version.
