Background: Enablement Updates

For blog readers who are perhaps not so familiar with the subject, here are some explanations. Microsoft publishes two feature updates every year, one in spring and one in autumn. In the past, these releases were released as 'full' feature updates for a long time – with the result that a fat upgrade package of several gigabytes had to be downloaded and installed from the Microsoft servers. In the install process, Windows 10 was completely replaced.

Since 2019, however, Microsoft has been trying to roll out the autumn update for Windows 10 as a 'small update'. For the first time, this was done with the 190x versions of Windows 10. The spring update (Windows 10 version 1903) came – in the old familiar manner – as a full feature update. But the autumn update (Windows 10 version 1909) was realized as a 'small feature update'. The code for the Windows 10 versions 1903 and 1909 is the same – even common updates are used. Instead of downloading gigabytes of code for a feature update, Windows 10 version 1909 was made available (for Windows 10 version 1903 systems) as an 'enablement update'. A small update package of about 500 kByte simply changes the version.

The same is done with Windows 10 version 2004. With the update KB4562830, Windows 10 May 2020 Update (Version 2004) is changed to the Autumn feature update, currently called Windows 10 20H2. So the update virtually only releases the 20H2 features already contained in Windows 10 Version 2004.

    Something called an Enablement Update would, to me, constitute a small update that merely flips a switch that tells a bunch of code to activate in place of legacy code. There is no memorandum to the users that I am aware of that defines an Enablement Update in that way. Formerly, some updates would take a long time to download and a long time to install. Now Microsoft can include bits and pieces in updates over a long period of time with most of the bits and pieces inactivated awaiting an Enablement Update. That's my surmise. Perhaps Microsoft will do me and millions of other users the favor of confirming my suspicion or explaining how it is really done.

      See the addendum I've added at the end of the text. It has been confirmed by a developer session to interested people for Win 10 v1909 – and is the same for Win 10 20H2.

    This doesn't help me understand what new features are "enabled" with this update at all. I don't understand why none of the articles about this enablement package actually go to the trouble of explaining what these mysterious new features are.
