Is working with the mouse and keyboard at times too sluggish for your liking? Well, Windows 10 is a touchscreen-optimized operating system (just like Windows 8 was), so with just a finger prod, it can do a lot of cool stuff rather quickly.
Swiping in from the left, for instance, will take you to Task View, an overview of all currently running apps. Swiping to the right brings up the Action Center, where updates are displayed and you can change your settings. Swiping down from the top generates a title bar complete with instruments for minimization.
Go to the Cortana/search box to view the full range of gestures available, and search for 'touch'.
