Are you unhappy with the functionality of your desktop? Are the menus distracting, the system slow to start, etc? Would you rather have a minimal layout? A faster boot speed? In that case, you need to look at the window managers available for Linux users.

Window Managers are essentially the programs that control the way your menus and windows are arranged, moved, etc. They can completely change the feel of your computer, and be used to optimize your workspace for whatever you need it to do.
