It's up to you, but when I bought a Windows 10 laptop after my windows 7 bit the dust (it still worked, but the keys kept snapping off
)
I was unable to play Skyrim, and still am. I kept getting an error about the path not available, even after re-installing the game and doing a search on the error. And Warcraft always seems to be laggier and a lower fps than when I played it on my Windows 7 computer. I'm thinking of just re-installing 7, because I like the look and navigation of it a lot better, and personally for me, my games were slower. Of course you can do the trial and see what you think!
