The Windows 8.1 (New) Start Button
The Windows 8.1 Start button isn’t your grandpa’s Start button. That is, the Windows 8.1 Start button doesn’t display a menu of your applications the way it did in previous Windows versions. Rather, a click or tap on the new Start button displays your Start screen.
Windows 8 introduced some big changes compared to earlier versions of Windows. One of those changes was to eliminate the Start button, which had been around since the introduction of Windows 95. Windows 8.1 has a new Start button.
Although most people would probably associate the Start button with the Windows desktop, in reality the Windows 8.1 Start button can be seen in the lower-left corner of your screen, regardless of whether you are currently viewing the desktop or the Start screen.
Pressing the Windows key on your keyboard also displays the Windows 8.1 Start Screen. Although some users don’t like change and miss the Start menu, the Windows 8.1 Start screen actually makes finding and opening your apps easier to do than it was in earlier Windows versions.
