Extract = what's found in image
Clean image (minus) Extract = what's missing
You can only use [what's missing] to apply to a new ISO.
So I can't simply select my Current Preset in the Host Refresh dialogue? I don't want to put back what's missing. (At least, I don't think that I do.) I want to remove from the vanilla wim what I have removed from my current wim.
(I made screen recordings to try to make a video to show others how to do all this. But since I don't know how to do it yet, I can't make a video.)
