The Start Button is a key feature in the operating system of many computers, particularly in the Microsoft Windows environment. It serves as a central hub for accessing programs, settings, and files. Users can click the Start Button to open the Start Menu, where they can find applications, search for documents, and manage system settings. Introduced in Windows 95, the Start Button has evolved over the years, adapting to user needs and design trends. It typically appears in the lower-left corner of the screen and is often represented by a Windows logo or a simple icon. The Start Button enhances user experience by providing quick access to essential functions.
