Concerning my initial post, it appears that version 184.108.40.206 had a bug in the AIO Add Updates and Subfolders feature. Using 220.127.116.11, I was able to add the entire IE10 structure to the build. Assuming it went first in the sequence, what seemed complex is relatively easy if the tool is working. Sorry for distraction.
New to this tool and finding your guide quite helpful! Since you posted the initial process, MS has released IE10 for Win7. The folder structure downloaded from McRip seems fairly rich in sub-folders and file types. it would be quite instructive to get some insight into how this would be integrated. Thank you for sharing
