This past week Microsoft released the Patch Tuesday updates for Windows 10 and also for Windows 11 for the month of November. Besides Patch Tuesday, the tech giant also released new dynamic updates to improve the WinRE on Windows 11 21H2, as well as Setup files for all Windows 11 versions, ie, 23H2, 22H2, and 21H2.

Besides Windows 11 though, Microsoft this time also released a dynamic update for Windows 10 as well which is meant to improve Setup binaries. The last such dynamic update for Windows 10 was released back in July via KB5028311.

Microsoft writes in its support article:

KB5032906: Setup Dynamic Update for Windows 10, version 21H2 and 22H2: November 14, 2023


This update makes improvements to Setup binaries or any files that Setup uses for feature updates in Windows 10, version 21H2 and 22H2.

In a Tech community blog post about Windows 10 Dynamic Updates, Microsoft explained Dynamic Updates in more detail regarding its various components and uses. These packages include fixes to Setup.exe binaries, SafeOS updates for Windows Recovery Environment, and more:

As soon as a Windows 10 feature update initiates, whether from media or a Windows Update service-connected environment, Dynamic Update is one of the first steps invoked. Windows 10 Setup reaches out to an Internet-facing URL hosted by Microsoft to fetch Dynamic Update content, then applies those updates to your OS installation media.

Content acquired includes:

  • Setup Updates: Fixes to Setup binaries or any files that Setup uses for feature updates.
  • Safe OS Updates: Fixes for the "safe OS" that are used to update Windows recovery environment (WinRE).
  • Servicing Stack Updates: Fixes that are necessary to address the Windows 10 servicing stack issue and thus required to complete the feature update.
  • Latest Cumulative Update: Installs the latest cumulative quality update.
  • Driver Updates: Latest version of applicable drivers that have already been published by manufacturers into Windows Update and specifically targeted for Dynamic Update.

In addition to these updates, Dynamic Update will preserve Language Pack (LP) and Features on Demand (FODs) content during the upgrade process. These are not updates to LPs and FODs, but reacquisition to ensure the user has these elements present with the update completes.

These updates are installed automatically but they are also available from the Microsoft Update Catalog website for manual download at the following links: KB5032906.
