Pin apps to the Start menu to see live updates on what’s happening in your world—such as new email, your next appointment, or the weekend weather. When you pin an app, it's added to the Start menu as a new tile.
Select the Start button, then press and hold (or right-click) the app you want to pin.
Select Pin to Start.
Once you pin a new app, resize it. Press and hold (or right-click) the app tile, select Resize, and then choose the tile size you want.
Tip: Drag and drop apps from the apps list to pin them to the Start menu as tiles.
