First let me apologize up front as I am sure this has probably been answered many times and it is just a comprehension issue on my part as this is all completely new to me. First, what I am trying to do is create an image of win 8.1 pro with media center with drivers, updates, and serials integrated. Maybe beyond that I would like to additionally add office 13 and a few other programs. I have been working on this for about two weeks and I feel like I am just not seeing the answer and it is probably in front of me. I managed to get an ISO of winpro x64 with media center and serials integrated (although this is a bit of an assumption as I have not tested the ISO) but I was previously trying to use a different tool and I kept getting an error in regards to the install.wim. Well, after a lot of reading I found that in 8.1 the install.wim is now install.esd so I start trying to figure out how to get through that which ultimately led me here and to wintoolkit. I was thinking that if I worked through getting a install.wim file I could just replace my install.esd with the install.wim that I created. Now, I finally worked through getting the .wim created but in getting this far I am not so sure I can just change out the .esd for the .wim in my already created ISO. When working with wintoolkit it looks like you integrate your items into the .wim file. So, do you integrate it there and change it into an ISO for install somehow? This is really where I feel like I have become lost and I just don't have the knowledge to interpret the answer on my own. At this point I am wondering do I convert the .wim to an ISO and just start over with integrating serials, drivers and such. Ugh, as you can see I am not the sharpest knife on this topic. I hope I'm not beyond help
