I tested the iso in a vm. It's very good. It's a good tool that harkaz has done, I hope some users will buy it on the forum. More than 2gb have been deleted from the winsxs folder I had trimmed down. Maybe Microsoft would be interested in this tool. With a normal iso, the install of windows takes up roughly 14gb. This one only takes up 8gb. For a big hdd, it's not significant, but on a ssd of 100 or 200gb, it's a difference.
