Hello and regards to all the users here. As I am a novice in that matter and here in this wonderful social site, I beg for your pardon if I am not writing in the right place of the forum but I am just desperate for an answer. Let's say I have the mentioned iso which containes 26 indicies inside it, both x86 and x64 and it supports both English and German Language (dual language installs). It has almost all Windows 10 1809 sku's inside, except the Enterprise 2019 LTSC (x86&x64) and Enterprise 2019 LTSC N (x86&x64). How it will be possible to add these skus to the already completed iso and to be booable again. How to upgrade this iso, so to contain the LTSC indicies, which is the process? Is it possible at all, is there any fast way to be done or the sweat to make it does not worth it. Took me a lot of time and effort, research to make it right, but it seems that trick is elusiver than it seems. Will be happy and appreciate of any help on that matter, because for now it seems immposible to me and I am ready to quit it. Many Thanks!
