I am new user to hp my friend recommended me to buy hp brand because it's price is low compare to other.it's been a month and I am using this brand but having bad experience it's pri installed as win10 runs smoothly however, I have been getting a lot of trouble after installing windows 8.1.the software more often get crashed and it doesn't support some software.plus, I tried to install linux but same problem.it only support win10 os that's bad.
