Out of curiosity, why are you giving your nephew a machine running Mint when he doesn't seem to want or need a Linux machine, and would want to be using a Windows machine?
It kind of feels like you're making a point that using a Linux kit is a mistake because you'd rather use a Windows one. Which... well... obviously. If you want to use Windows, you want your machine to look and function like Windows, you want to run Windows apps and you want to run Windows games, then yeah, you're better off using Windows.
