The Start screen replaces the Start menu in Windows 8. You can pin apps, contacts, and websites to Start to easily access what you use most. All of your apps—both apps you install from the Windows Store and desktop apps—are available from the Start screen. You can organize, group, and name categories of apps in whatever way makes sense to you. Tiles and notifications show what’s new so you can get important info and updates at a glance.
You can get to the Start screen by swiping in from the right edge of your screen and tapping the Start charm or by pointing your mouse to the upper-right corner of the screen and then clicking the Start charm. You can also use the Windows key on your keyboard ( Command key on Apple keyboards) to go to Start.
