I already tried that, the numbers did not add up. I just downgraded to 8.1 and everything is fine again. My RAM usage is correct and what not and i'm happy. Unfortunately i don't have the great UI of W10, but i'm down with 8.1, i don't mind it too much.
So what seems to be the obvious answer is that my computer doesn't go well with 10 like others do. Perhaps it's a glitch.
