This laptop came in great physical condition but upon booting up and setting up windows 10 for the first time, windows defender was going bonkers that there were threats.  Ended up being 28 Trojan horses embedded into dell drivers. I contacted Amazon and got a partial refund in order to keep it, bought a new windows 10 license and formatted the HD and reinstalled windows 10!  Be aware of refurbished computers that they aren't doing shady stuff to steal your data or build a bot net.
