Multitasking has become a necessary skill in order to be successful nowadays. We might need to work on two or multiple applications at the same time.
Windows 10 has a functionality called as Split screen which would help you achieve that purpose. One could basically open two windows side by side and work on them simultaneously.
In order to use the split screen feature type the Windows key and the left arrow. This would push your window to the left and it would take 50% of the screen width. Once that is done, Windows would allow you to choose which application you would like to have as the second window.
