Use WinTray to save valuable taskbar space.
When the taskbar is clogged with multiple buttons for all those open windows, WinTray can be used to hide them as system tray icons, saving space. Easy access is provided to the hidden windows through hotkeys or their system tray icon (or both).
WinTray can even be set to apply hotkeys and/or system tray icons when it starts up. Use WinTray to save you space and to hide windows from view when they’re not needed.
This program is freeware.
