📎 AI Summary:
The thread discusses methods for integrating Windows 10 updates into a custom ISO. The original poster asks how to manually apply a cumulative update to an extracted ISO directory and later create an ISO from it. Contributors suggest using tools like NTLite or the DISM command-line utility to inject updates into the install.wim file, with some recommending simply updating the latest ISO directly for convenience.

Assume I download the base ISO for Win10 v1903 and extract the content into a directory (tree).

Then I download a cumulative Update package for this Win10 version.

How can I apply this Update package to the just extracted ISO Win10 directory tree?

How can I later make an ISO out of this update Win10-directory tree?

Why not just download the latest ISO on keep it on a USB. I do and each time there's a new patch/update I just download it and let it re-write it to the USB.

NTLite is a good option for doing something like this (custom ISO). But yes @bassfisher6522 makes the most sense with that.
