A taskbar is a graphical user interface element in operating systems, such as Microsoft Windows, that displays running applications, open windows, and system notifications. The taskbar is typically located at the bottom of the screen and provides quick access to frequently used programs, files, and settings. The taskbar also shows the system clock, system tray icons, and the Start menu, which allows users to access programs and features installed on their computer. The taskbar can be customized, allowing users to add or remove shortcuts, adjust the size and position of the taskbar, and choose between different display options, such as using small or large icons, and showing or hiding labels. The taskbar is a fundamental element of the Windows desktop, and its efficient use can improve productivity and organization.
