Windows 10 is the next major release that addresses many of the shortcomings of Windows 8. It’s also the operating system that brings familiar features like the Start menu and apps floating on the desktop found on Windows 7. However, it’s also an operating system with new features, such as Cortana, Action Center, tablet mode, Settings app, and Windows Store apps.
