1. The Start button was first introduced with the release of Microsoft Windows 95 and featured in all releases of Microsoft Windows. The Start button allows users to access their computer programs or configure Microsoft Windows easily.
The picture to the right shows different examples of the Start buttons found in Windows. The gray Start button at the top was the first Start button, found in early versions of Microsoft Windows. In the second picture, this Start button made a brief appearance in Windows XP. Next, Start was removed, and the button was made into the Start Orb, which just had the Windows logo in a circle and used with Windows Vista and Windows 7.
Note: In the initial release of Windows 8, the Start button has been replaced by the Start Screen. Later versions of Windows 8, more commonly referred to as Windows 8.1, have a Start button (shown in the image) that opens the Start Screen instead of the Start Menu.

Where is the Start button and what does it do?
By default, the Windows Start button is found at the bottom left part of the desktop screen. However, the Start button can be placed at the top left or top right part of the screen by moving the Windows Taskbar. Clicking the Start button opens the Start Menu (except in Windows 8) that gives you access all the programs installed on the computer and other Windows features. Below is a visual example of the Start button and its location on Windows 7.
