I have a laptop running an Intel Core i3-3110M @2.40 GHz, 4GB RAM, 500GB HD. Should I upgrade to Windows 10? It upgraded once, without me knowing it (dammit Microsoft), and ran incredibly slowly for 5 mins. I went back to 8.1, because I didn't really want to upgrade then anyway. Is Windows 10 faster on a slow laptop, or would Windows 8.1 be the better choose (bare in mind I do light gaming on this machine, such as low settings TF2, Age of Empires 2 HD or anything similar).
