A long time ago, windows 8 days. Someone was able to make a modified wim that was basically just the recovery portion of the win 8 installer. (the special reboot screen you get if you hold shift down on windows 8+) basically from there you could also run commands, .exes, portableapps, with the help of a little loader baked in. I have the wim if you would like to look. But I wonder if there could be a way to do this with windows 10 to use with utilihack so we dont need a full win 10 ISO to use?
