then after hitting the enter, you'll get into the system configuration app and go to "Boot" 

then in the Boot menu click the "Advanced Options"  then set the number of processors at max number. You may check the box in the maximum memory if you want to load and maximize the power of your RAM (Note: Setting the number of processors at max and loading the maximum memory of your laptop consume more power in your battery and decrease your usage time. )

then after setting it on. click "OK" and you'll be back at the System Configuration. Then go to  the "Services" and check the box in the "Hide all Microsoft services". 

Unchecked all apps that you are not familliar with and checked those apps that are connected to the games and browsing experience.
