For example, let's say you snap a window to the right half of your screen, leaving the left half of your screen blank. If you snap a window with the mouse or the keyboard and you're left with a partially empty screen, Windows 10's Snap Assist feature will pop up. If you press Windows Key + Down Arrow, you'll minimize it.

Now if you select a window and press Windows Key + Up Arrow, you'll maximize the window. In a previous build of Windows 10, you could also vertically snap windows into either the upper or lower half of the screen, but in this build it's no longer possible. Once the window is in its smallest possible state (a quarter of the screen), you can move it around using Windows Key + Arrow Keys. If you want to snap it into one of the quadrants, first snap it to the left or right side of the screen and then press Windows Key + Up Arrow or Windows Key + Down Arrow to get it into the top or bottom corner. To snap a window with the keyboard, select the window you want to snap and press Windows Key + Left Arrow or Windows Key + Right Arrow to snap that window to the left or right side of your screen. You can also snap windows using keyboard shortcuts. You can also drag it to a corner to snap it to the corresponding quadrant, or drag it to the top of your screen to get a full-size window. Drag it to the left or right side of your screen to snap it to the left or right half of the screen. An outline will appear to show you where the window will snap to once you drop it. To snap a window, click its title bar and drag it to the edge of your screen.

In Windows 10, Microsoft has improved the snap feature to include more options. The feature lets you 'snap' a window to one side of your screen without having to move it around and resize it manually. Window-snapping, which was first introduced in Windows 7, is a pretty convenient feature for quickly maximizing your screen's real estate.
