From what I can see, this file comes from the Treshold 2 Update for Windows 10. Sadly, I still do not have it installed on my desktop computer (I have no idea why). I'll need to download it using the Media Creation Tool, extract the .iso and the .wim file. It'll take a while. I'll work on that tomorrow evening (since I work in the day). In the meantime, I can also ask if one of my colleague have Treshold 2 installed and can source that file for me.
