Definition is simple. A plethora of OS components that will never be used and were installed by default. If it was just an app or two, whatever but your start menu in its default configuration, even in Windows 10 Pro for Workstations, is a cluttered mess. I would pay for Windows 10 Pro for Workstations if it was stripped down to the bare OS and during install gave you the option to install stuff like Defender, Store, system restore .... If they want to offer Windows 10 Home loaded to the gills with default apps then it only makes sense that OS versions designed to be a work environment not come with that BS.
