I downloaded en_windows_8.1_with_update_x64_dvd_6051480.iso from GezoeSloog's collection at Cloud Mail (Windows 8.1 with Update 3) and the SVF patch for the desired language, but checking the image with DISM, I noticed it only contains two WIMs: Home and Pro SKUs in it. Does a more complete Technet/MSDN ISO exist, with the remaining SKUs, such as Home Single Language and Enterprise? I don't mind not having Volume Licencing, Bing and China WIMs. Just for comparision sake, I also downloaded Windows 10 Version 2004 image from his library, and it's a complete image, featuring Home, Home Single Language, Education, Pro, Pro Education and Pro for Workstations WIMs. Thus, I'm baffled why the Windows 8.1 image is not complete. If such multi ISO does indeed not exist, what's the best way to create a comprehensive ISO like the Windows 10 one? From ESDs? Thanks in advance.
