Snap Assist
Snapping your windows to quickly resize and reposition them on your screen has been around since
Windows 7, but it’s received some enhancements with Windows 10. You can snap your windows
vertically and horizontally; when doing so, you’ll be prompted to select what window you want to snap
into the empty space. It’s a small touch, but one that helps make for a smoother experience.

Of more note is the ability to snap four windows into a 2×2 grid. You can use keyboard shortcuts to
do so or just use your mouse. Of course, you don’t have to have four windows to use this mode. You
could have one window snapped vertically and then two stacked horizontally on the other side. For
those who often have a lot of windows and apps open, this will definitely help speed up productivity.
