I like the sound of your proggie as wimboot is a bit lets say "technical".. Also I did not really gain the space I was after or expecting.
With your Utility would it be possible to compress 1 partition, example..when installing windows I like 1 partition style layout, keeps the ssd clean (looking) in disk management and simpler if I want to restore a recovery image. What I mean is no windows system reserved separate partition.
Does your program require separate partitions in order to function or may I run the wimboot from 1 partition only ? This is the way I ran the "standard" wimboot and it functioned correctly, just not with the desired decrease in space that I was hoping for.
How much are we talking for 2 x licences as I could perhaps get 1 for my dad too
