You can copy your pics and docs to a dvd or a usb stick.
Note I said copy.....don't move.
Verify all your data made it safely to the media.
If you do a factory restore I suspect your going back to windows 8.
It's a rather drastic move is that what you want?
I would like to do a back up to save all my pics and documents before I restore to when it was brand New. Please tell me how to do the above. I have windows 10 before I had windows 8. Thank you in advance
