Vista and Offfice 2007

[Eagle117]

I've read through the WAIK documentation but I still don't quite get this. I want to make an image of Vista with Office 2007 and other business applications included in my WIM file to deploy. Somewhere I thought I read that you could then modify the WIM file afterwards to include or remove things such as programs and windows updates without having to reimage the machine. How do you get imagex to recognize programs or will it just do it if it can and skip it if not? Is it really as simple as installing Vista and my other programs and then using imagex to capture it and be done? How do I get them into modules or components that I can then include or remove?
