DISM is the windows servicing tool, it's in all editions. No need for other tools. MSMG also utilizes DISM for servicing wim files.
Yes, I've download many apps to use it with GUI, but I'm on W7 and it needs some files to work, also the specific for W10. The extracted WAIK files, avoids the needing of the whole GB pack. I have to read more, but that option if it's possible for my needs, is what I prefer.
MediCat is 27Gb +/-, but it's W10 Wim is 1.5, at least older version which is the idea to edit, at least the first. It needs, Drivers and other settings and software for my needs.
Ok, The Path on 20.10: ..\medicat.20.10.img\0.ntfs\Boot_an_Operating_System\[UEFI]_Mini_Windows_10.iso\sources\boot.wim Thank you.
Hi, For now I've managed to add some Drivers using NTLite. Still pending to find out to add some other modifications loading the Wim as Live OS.
