This computer was promised to ship with a full Windows 10 Professional edition installed, WITH a Recovery Partition. Five months in it needed a full Windows Update which it Would NOT complete, instead getting constant BSOD error crashes @ 94%.  Then began crashing constantly under any conditions!  It became completely unusable!  Having no other options I decided on a Recovery, and then discovered their Recovery Partition was totally blank!  Prior to this it could have been a 5 star, now I could only give it a Negative 5! If there were such an option :/
