What are Dynamic Updates?

Microsoft has introduced Dynamic Updates to help you dynamically integrate them when you upgrade from an operating system version to a higher version. These dynamic updates are then dynamically reloaded as needed during the installation of Windows 10 (or when a system is reset) in order to include any final fixes that are needed in the system during setup. Microsoft calls these patches Compatibility update for upgrading to Windows 10 and writes:

This update makes improvements to ease the upgrade experience to Windows 10, version xxx.

Such updates contain improvements to facilitate the 'upgrade experience'. According to this document, critical drivers and enhancements that help upgrade are provided through Dynamic Updates. Dynamic Updates are available through Windows Update and are automatically downloaded and installed. I've blogged about that with more details within my blog post Windows 10: What are dynamic updates?

The dynamic updates of February 19, 2019

As of February 19, 2019, Microsoft has released the following compatibility updates for its Windows 10 versions 1703, 1709 and 1803 as dynamic updates:

Details of what these updates really improves are not disclosed by Microsoft. Usually, Microsoft does not make dynamic updates available for download either, since they are downloaded by Microsoft in the latest version during the Windows 10 installation.

If you still need the packages (e.g. for integration into an installation image), you can still download the packages from the Microsoft servers. For version 1703 I found the dynamic update in the Microsoft Update Catalog. The colleagues from German site have also added download addresses of Microsoft servers here.
