How to Disable Snap Assist in Windows 10

Snapping windows is a great feature. Drag a window to the corner or side of your screen and Windows automatically resizes it to fill that space. When you snap a window to one side of the screen, Windows presents a thumbnail view of other open windows that you can use to fill the other half. That’s Snap Assist and if you don’t like it, you can turn it off.
