I replaced my old windows 7 PC with a window 10 only since windows 7 is no longer supported and the same with new software. Old one worked fine. New one (this one) is slow, but I only paid $99 for a refurbished Dell same as my old one. Other than it being slow, everything is just fine. It worked right out of the box. They sent instructions on how to wipe the memory and start fresh, but that was apparently already done.
