Slipstreaming Updates into install media working from Linux

[Joe7]

I'm looking around to find a way for creating a windows 7 installation media with also all available updates included.
I found that a suggested way is by using DISM command:

GitHub - zguithues/Slipstream-Windows-Updates-Guide: This guide is intended to help others figure out how to slipstream updates into a windows update iso or usb device

I'd like to understand a bit better this procedure in particular how DISM slipstream command works behind the scenes, and try to replicate it from a Linux system. That's my goal: creating a windows 7 updated media using Linux native tools. An exception could be the use of some windows tool that can run on Linux via Wine.

If you could help will be really appreciated. Thanks in advance!

A Windows install drive or iso has many versions on it.
You must choose a version you want to slipstream the updates. You can repeat the operation to all the 4 Win 7 versions.
Dism is the windows tool to extract the version from the image (install.wim) and then slipstream the updates (more than 250).
It is already complicated under Windows. I would say it's almost impossible under Linux.

Another solution is to run Simplix after the Win 7 installation. Simplix is a single file (~850M) with all the updates. Very good
