You have to remember, there are actually 5 "separate" images in the WIM. Those images are reduced in size only because the files are reduced to only 1 copy. In other words, if you have 5 versions of the same kernel.dll, then one 1 file is reference by all 5 images. You can rebuild the WIM, however it can only reduce the size if there are the same files on each image. It might also do a mild recompression at the same time, but I am not sure on this one. This "hi" and "bye" is probably a result of test code put in there by Legolash2o at the time of importing the registry settings. You may want to make a comment to him on that. Yes. The install setup does wait. However, there is also an option in W7T that you can set on the installers of "not always installed". This just means W7T will ask you at the beginning of the installer section which ones you want to run. FYI, SoLoR Updates do have IE9 and "XP Mode". You just have to go the specific directories to get them. There is a specific updated installer for IE9 that includes all of the latest updates. You may have to look around for the correct one as I believe solar has include the "zeroth" version. There is an up to date one that I use. Yes, there is a tab for that in the AIO button under W7T. It is not a bug. The "off-line" registry is likely loaded to that spot in the current registry. The modifications are made to loaded "off-line" registry and then unloaded. (Also the result of the "hi" and "bye" issue noted.) Edit: I forgot to mention, it does not matter where the IE9 update gets added. Beginning or end, it works just the same. (FYI, I have tried both. It does not matter)
