Hp laptop is awesome laptop. I am asking that because I am currently using this product. mostly we suffer from many problem with our laptop like hanging, battery backup is not good etc. but if you buy this product you will not suffer from this kind of problem. its ram is boost. it is user friendly . I am fully satisfy from this product. if you suffer from any problem related to window if window is pre install you may yourself install window again and if your file store in local disk that file will not erase.
