Windows 10: What are dynamic updates?

[German]Sometimes Microsoft offers Windows updates, that are quoted as 'dynamic updates'. Here are a few details, what are dynamic updates are for.


I came across this term during updates KB4020001 and KB4020002 released recently for Windows 10 (see my blog post Windows 10 V1703: Updates KB4020001 and KB4020002). Both updates has been quoted as 'dynamic' in Microsoft's kb articles – but I was wondering, why none of those updates has been offered via Windows Update. One of my German blog readers pointed me to the right direction, as he mentioned, that it was 'dynamic updates' for upgrading Windows.

Dynamic Updates – for Windows Upgrade installation only

Microsoft has introduced dynamic updates to support an upgrade from a Windows install to a new operating system version. During setup it's possible to download dynamic updates and integrate them into the install process. According to this document critical drivers and other improvements for the upgrade may be released via dynamic updates.

In Media Creation Tool and during upgrades the install wizzard offers to download updates from Microsoft's servers and integrates it into the install process. This Technet article contains some details about 'Dynamic Updates' for Windows 8.x.
