Windows 10 is vastly different than its predecessors with a series of small tweaks and optimizations that makes this version such a departure from previous iterations.
Take the Snap feature as an example. Introduced in Windows 7, this feature allowed you to quickly maximize a window or line it up perfectly on one half of the screen by dragging the title bar to a particular edge of your display. While Snap is still present in Windows 10, it's got a few new tricks up its sleeve, which should help make multitasking quite a bit easier.
