Things like Windows Hello face login, clipboard history, touch-screen support, multiple virtual desktops, Quick Access in File Explorer, Cortana voice assistant, and even the Edge browser improve my daily computing. And in my experience (and that of many I know), it's been pretty delightful to use. The Windows 7 faithful have nothing to fear, though Windows 10 isn't much of a paradigm shift from the now-decade-old OS. 14, you won't have any choice but to upgrade to Windows 10-unless you want to lose security updates and support.
