Empty Documents and Settings

Hi all,
I did a little search here, and most result yeild roaming profiles.

Here is what we have and what I want to do. Our students have individual logins, and we have a couple group logins. We went from trying mandatory profiles and such on some accounts. Now, systems that were not imaged often keep the records of a mandatory profile and its setup, and since the profile no longer exist their desktops are empty.

We have all desktop shortcuts located in the All Users folder. So, what I need to do is clear the Documents and Settings of all the account except the Default (which is hidden so hopefully that won't be an issue) and All Users. That way windows had to re-make the desktop and setting based on those accounts.

I am not worried about the users settings, the kids are elementary level so they will not be making any important setting changes. My only concern are things like Office which prompt them for user details.

I would hopefully like a solution that could be run on a monthly, weekly, or daily process...depending on need. I would idealy like a GUI script that a lab teacher could use, because I have tried explaining to them to just delete the users folder on the system with problem...but that doesn't sink in...and I am tired of chasing behind the kids with problems and trying to delete the right folder.

Could any make some solution suggestions, or perhaps what specific files I could delete (I guess if the desktop is the issue I could just remove the "desktop" folders content, but what prevents it from pulling from "All User/Desktop"?)

I hope I am clear enough, FYI its one particular account that had a mandatory profile at one point, I check the ntuser file and it is a .dat, not a .man ....so not sure why it is not loading the All Users/Desktop folder as it not a mandatory profile anymore.
