Docking Apps to the Left or Right of the Screen

When you drag an app in from the left of the screen with your finger, you will see a vertical bar appear in the left quarter or right quarter of the screen, depending on where you are dragging it at that point. Dropping an app when you see this bar will dock it to the far left or the far right of the screen. You can also drag the currently displayed app downward from the top center of the screen to dock it to the left or right of the screen.

Note: To close the currently running app, drag it downward from the top center of the screen with your mouse or finger, and throw it off the bottom of the screen.

If you then return to the Start screen by pressing the Windows Key, the next app you run will fill the remaining space, so you have two apps side by side. You can drag the vertical bar separating them left and right to switch the focus from one app to the other, or to move one app off the screen completely.

To dock apps side by side using a mouse (this also works with touch), drag the app from the top center of the screen toward the center of the screen. You will see the app change to a thumbnail image. You can now drag this thumbnail to the left or right of the screen and drop it when you see the vertical dock bar appear. 

If you have a large enough screen (this just won’t work if you don’t), you can arrange up to four apps on screen. When you are running two apps side by side, if you launch a third app it will appear as a thumbnail between them. You can drag it left or right to replace the running app there or, if you hover between the running apps you will see a space open into which you can drop it.
