If you left-click or hit the Windows 8.1 Start button, you will open the Start Screen and access all your apps. Interestingly, if you have multiple monitors connected to your computer, clicking the Start button opens the Start Screen on the screen you clicked on. In other words, you can open the Start Screen on any screen you want.
Left-clicking on the Windows 8.1 Start button works as if you pressed the Windows key on a keyboard. In either case, the Start Screen opens on the currently active screen.
YOU HAVE THE RIGHT TO CLICK.
Right-clicking on the Start button in Windows 8.1 brings up a pop-up menu with some exciting choices. Yes, it doesn’t look like the old Start Menu, but the pop-up menu will make it easy for you to access things like Task Manager and Control Panel. You need to click on the item you want from the pop-up menu.
YOU CAN OPEN TASK MANAGER FROM THE START BUTTON.
An excellent example of how you can use the new Windows 8.1 Start is to open Task Manager to see and control which applications are running.
Right-click the Start button and choose Task Manager from the pop-up menu to display the Task Manager window. You can then select a running task from the list and click the End task button to shut down the application chosen.
YOU CAN TURN OFF WINDOWS FROM THE START BUTTON.
You can also shut down or restart the computer using the right-click menu from the Start button. Select the Shut Down option at the bottom of the menu and then choose the submenu’s shutdown option.
