I can never find it when I need it most. It’s there when I need to shut down (another oxymoron), but when I need to turn on & START my computer it’s just not there. (Pressing the <Any Key> doesn’t either work.)
You’ll have to go to ControllPanel, Devices, Computer, OperatingState, On. When prompted with, “Are you sure you want to use this computer?”, click on “I think so”.
