Microsoft improves Windows 11 Setup, Recovery with KB5045520/KB5044612/ KB5045525/KB5044617

This past week, Microsoft released Patch Tuesday updates for October 2024 for Windows 10 (KB5044273 / KB5044277 / KB5044293 / KB5044286) and Windows 11 (KB5044284, KB5044285, KB5044280). The company also published a new media creation tool update with the latter.

The Patch Tuesday update for Windows 11 fixes the bug that led to boot loops and Bluetooth/USB connectivity failures. And Microsoft has also promised an upcoming fix for the SFC scan error. However, certain quirks are yet to be addressed including a BSOD issue on WD HMB-based NVMe SSDs and an undeletable 8.63 GB pre-upgrade data.

As always, aside from Patch Tuesday, Microsoft has also released new dynamic updates for WinRE (Windows Recovery Environment), also called Safe OS updates, and Setup updates. This time there is a whole bunch of them as there are updates for all Windows 11 versions, namely, 24H2, 23H2, 22H2, and 21H2.

First up we have the setup binary updates:

For those who may not be aware, these Dynamic Update packages are meant to be applied to existing Windows images prior to their deployment. In a Techcommunity 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).

 

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 dynamic updates are not pushed through Windows Update and are only available for manual downloading from the Windows Update Catalog website. You can find them here: KB5045520, KB5045525, KB5045527, KB5044612, KB5044617, and KB5044619.
