The system tray is a section of a computer taskbar that typically displays the clock, volume control, anti-virus software, scanner software, channel viewer and system resources indicator. The system tray is a feature of the Microsoft Windows desktop user interface and was first introduced with the Windows 95 operating system.
The most common interface displays the system tray at the bottom right of the computer screen, though it may also appear in a horizontal format if it contains additional programs. Users generally interact with applications in the system tray by double-clicking or right-clicking the icons. When a user minimizes a program, it shrinks to the system tray rather than to the main taskbar.
