Anybody know how to use Norton Ghost?

I just learned that Norton Ghost was on my computer. Does anyone know how to set it up so that i can run the Ghost and my computer would have only the settings and files that i installed. This is popular for Universities where they just run the Ghost at the end of the day, and it deletes everything that was put on the computer after you made the settings. Hard for me to explain. If i install photoshop, then put it in the settings in Ghost, then download other programs, and i decide to clear up my computer to free up space, i run ghost, and photoshop is still there, but everything else that was installed after that point is gone. Sorry about that, can’t explain it very well. Do you know where i can learn how to do this? :slight_smile:
