if you had you haul around a 7' tall vagina I would not complain if you made $x0.000 to do so

The best thing to do would be to install Windows SteadyState

It's designed for shared computers, but once set up it can reset the computer back to the default state on each boot, perfect for a parent or child without great computer skills. It's a free download too. Not sure but I think it can be set to allow saving to a particular drive or folder to at least allow for some permanence of data.
