Then you click Power, and finally Shut Down. So even in Windows 10, you have to click 'Start' to shut down your PC. But that's still what it's called, and still how Microsoft refers to it. Granted, the Start button is no longer labeled that way, having evolved into a Windows-logo button back in Vista. It must be a point of pride in Redmond that even after all these years, you still have to click 'Start' to shut down your computer.
