CCGuy Exactly... Maybe my terminology is off, but that is exactly what I was stating before. I am moving towards DataImages. From what i read from your post, it sounds like you are taking the install.wim file and injecting stuff into them. That is not my understanding of DataImage. My understanding of Dataimage is you create a custom WIM file and associate it in your unattend.xml file. Once the system comes up, the files get extracted to the root of the systemdrive. In my opinion, it doesn't touch the actual source, install.wim. Now the tricky part is how to dynamically create a dataimage and then associate it in your unattend.xml file. How does that sound?
