Understanding Dynamic Updates
For those unfamiliar with Dynamic Updates, these packages are intended for application on existing Windows images before deployment. Microsoft has outlined these updates in detail within a recent Tech Community blog post, explaining their various components and purposes.
Dynamic Updates initiate at the start of any Windows 10 feature update, whether launched from media or a Windows Update-connected environment. The Windows 10 Setup reaches out to Microsoft’s Internet-hosted URL to retrieve Dynamic Update content and then applies these updates to the OS installation media.
Included content is as follows:
- Setup Updates: Fixes to the Setup binaries or files used during feature updates.
- Safe OS Updates: Fixes for the Safe OS utilized in Windows Recovery Environment (WinRE).
Additionally, Dynamic Updates preserve Language Pack (LP) and Features on Demand (FOD) content throughout the upgrade process. It’s worth noting that these updates do not modify LPs or FODs but rather ensure their reacquisition to maintain user access once the update is complete.
Accessing the Updates
The Setup updates can be manually downloaded from the Windows Update Catalog. Users can find them via the following links: KB5053424 / KB5053485. The WinRE updates are also available for manual access at KB5053426 / KB5052424.
