You have several programs open and you don't want to miss anything! In Windows 10 you can quickly snap windows next to each other so you can split the screen evenly between 2 - 4 applications. Using your keyboard: Hit Windows + Left Arrow to snap a window to the left side of the screen or Windows + Right Arrow to snap it to the right. If you want your application to take up a quarter of the screen, hit Windows + Up Arrow or Windows + Down Arrow after you snap it to the left or right and it will move into the corner, taking up less room. Using your mouse: drag a window all the way to the left or right side of the screen if you want it to take up half or into the corner if you want it to take up a quarter of the space.
