To turn this feature on, open Settings ➜ System ➜ Multitasking and turn this on. You can also customize some other options there. Next, drag any opened window to one of the corners i.e top-left, top-right, bottom-right, or bottom left. This will resize your window and place it to the corner where you have dragged. If you feel that these four windows are too small for your screen size. You can just drag it to the left or right corner and this will open only two windows at a time. This enables us to do multitasking, like watching some videos on the side while writing some text on another splitter windows. That’s the reason why we have listed multitasking in our windows 10 tips and tricks lists.
