What is FancyZones and why use it?

FancyZones is just one of many features offered by Microsoft’s PowerToys, a very popular power-user tool that includes a set of utilities that can modify how Windows works. The main reason to use FancyZones is that it can help you create custom window layouts on your screen and quickly snap your windows to these zones.

Instead of manually resizing and positioning each window, you can create predefined zones that automatically adjust windows to fit specific sizes and positions, thus effectively setting a default size for any window.
