How to make it use?

[CmPunkMessi]

Hey guys I am buying a laptop as (recommend by experts on this site).The specs are:
i5(7th gen)
16gb ram
Windows 10 home (the inferior model with 8gb ram has Windows 10 pro;so does Windows 10home and pro reallly make a difference)
2tb storage
Nvidia 940mx 4gb(discrete)

My question to you guys is,since by basic usage will be playing games not released in PS4,so is there any way my graphic card can use both system's and its own ram while game?

There isn't a big difference between home and Pro when it comes to gaming.

the system has such a thing as shared memory, in that it already is set up to use part of your systems ram for gaming. You can't increase it

it appears the card has 2gb onboard and can use another 2gb of system memory
