	Start Menu The Start menu is a graphical user interface element used in Microsoft Windows since Windows 95 and in other operating systems. It provides a central launching point for computer programs and performing other tasks in the Windows shell. It is named ''Start screen'' in Windows 8. It has been co-opted by some operating systems (like ReactOS) and Linux desktop environments for providing a more Windows-like experience, and as such is for example present in KDE, with the name of ''Kickoff Application Launcher,'' and on Xfce with the name of ''Whisker Menu''.

Introduced on October 23, 1999, it was promoted by Apple as "The Best Internet Operating System Ever", highlighting Sherlock 2's Internet search capabilities, integration with Apple's free online services known as iTools and improved Open Transport networking.
