How it works

In order to extract the Windows version from an ISO, we first need to mount the ISO file and open its content. In the ISO, there is a ./sources/ folder containing a Windows imaging (WIM) image in ./sources/boot.wim. When we uncompress this archive, we get a lot of files, but one file at the root of the archive stands out: '[1].xml'.

boot$ ls -lha
total 52K
drwxrwxr-x 5 podalirius podalirius 4,0K janv. 18 00:17  .
drwxrwxr-x 4 podalirius podalirius 4,0K janv. 18 00:17  ..
drwx------ 8 podalirius podalirius 4,0K mars  19  2019  1
-rw-rw-r-- 1 podalirius podalirius 3,9K janv. 18 00:16 '[1].xml'
drwx------ 8 podalirius podalirius 4,0K mars  19  2019  2
drwx------ 2 podalirius podalirius  32K janv. 18 00:16 '[DELETED]'

This file is a XML file containing information about the images contained inside the ./sources/boot.wim file. It contains all the information we need to know which major or minor build this ISO file is. Here is an extract of the '[1].xml' file:
