I've noticed that Windows 8 seems to be running Maintenance an awful lot. It seems every time I leave my computer idle it's start up the Maintenance. Even when it's not idle it starts running. At times I've left my laptop idle & returned only to find it extremely hot, & it generally doesn't get hot even when I am running game & what not. I've even noticed Maintenance running when I am on a low battery.
What is this "Maintence" doing all the time & why can't I turn it off?
