Ah laptops... Older than 1.5 years, I wouldn't recommend upgrading to Win10. My own laptop, 3 years old, was barely able to work when I upgraded. No drivers for anything at all. Had to downgrade back to Windows 7.
If all else fails, you could download the Windows 10 Beta Version of Minecraft. However, you will either have to do the free trial or pay $9.99 for the whole game.Minecraft: Windows 10 Beta VersionLike I said, make it a last resort. Until then, see what else you can find as I'm out of ideas myself at this point. -_-
I have decided to just return to Windows 7, Windows 10 is not worth all this hassle.
