in a technological community Blog post Regarding Windows 10 Dynamic Updates, Microsoft has explained Dynamic Updates in more detail about its various components and uses. These packages include fixes for Setup.exe binaries, SafeOS updates for the Windows Recovery Environment, and more:

Once a Windows 10 feature update is initiated, either from media or from an environment connected to the Windows Update service, dynamic updating is one of the first steps triggered. The Windows 10 installer reaches a web-facing URL hosted by Microsoft to fetch dynamic update content, and then applies those updates to your operating system installation media.

Purchased content includes:

• Install updates: Fixes to setup binaries or any files used by the installer for feature updates.
• Safe operating system updates: Fixes for the “secure operating system” used to update the Windows Recovery Environment (WinRE).
• Service stack updates: Fixes needed to address the Windows 10 service stack issue and therefore required to complete the feature update.
• The latest cumulative update: Installs the latest cumulative quality update.
• Driver updates: Latest version of relevant device drivers already published by manufacturers in Windows Update and specifically intended for dynamic update.

In addition to these updates, Dynamic Update will preserve Language Pack (LP) content and Futures on Demand (FODs) during the upgrade process. These are not updates to LPs and FODs, but a repurchase to ensure the user has these elements upon completion of the update.

These dynamic updates were automatically downloaded with the Windows 11 September Patch Tuesday updates. You can also download them manually by visiting the Microsoft Update Catalog website (KB5030326 / KB5030327).
