- Let me explain what I have done so far. First of all: I have a Win 7 Pro system and use KB extractor v1.2.0.0.
- When I extract KB 4474419 (for Windows 7) then in the folder "Extracted" a total of 2139 files and folders show up. Of those 2139 files 512 are (sub-)folders each containing one or more files (e.g. *.dll & *.dll.mui). The rest of those 2139 files (in "Extracted") are *.cat, *.mum and *.manifest files.
- When I try to open KB 4512938 (for windows 8.1 only) with the "KB Extractor" tool (v1.2.0.0) then I get 83 files of which 11 are folders. And only 2 of those folders do contain one or more files. Of those 83 files 72 files are *.cat, *.mum and *.manifest files.
- This behaviour makes me think that "KB Extractor" uses some extraction algorithm that's build-in in Win 7, Win 8 & Win 10 (didn't try a *.MSU file that was meant for Win 10) but that Win 8 & Win 10 system use a different extraction algorithm to extract the *.MSU files. And then "KB Extractor" version 1.2.0.0 "gets confused".
- When I use "Universal Extractor" (on my Win 7 system) then a different set of folders and files emerge. It's even different from what e.g. KB_Extractor produces. But both seem to "go off the rails" when it comes to properly extracting files from a *.MSU file.
