just make the system setting like form factory.
Can't have it both ways.  "Refreshing" w/o deleting programs and restoring to factory level are 2 different things.  Also, it depends on which OS system you have.  You did not mention this in any of your postings nor have you included your system info.
You have to decide which do you actually want to do?
Archive & Install (if your OS allows)
Erase the HD (restore to factory level)
