Like most of Linux OS, Mac OS X has a great feature names Spaces that lets you group applications/opened files and keep your working space uncluttered and organized.
Sadly, Windows doesn’t have this feature but there’s good alternative for Windows users to keep their desktop organized and clean.

It lets you manage and group your desktop into multiple desktop spaces for different purpose (like working desktop, entertainment desktop, personal desktop…). This is very useful for advanced Windows users.
