I have been working on getting Windows 7 setup for deployment and have learned quite a few things over the last few months. I still have a few questions and I'm hoping someone can help me with these. Currently it takes me about 4.5 hrs to create a basic image for deployment. I would like to not have to reinstall Windows 7 each time that I need to make a change to the default user profile. Is there a way that I can do this?

i.e: Remove the User Files (aka My Documents) from the desktop after I have already enabled it?
