Minimize applications to System Tray
Once you have downloaded and simply run the portable app RBTray. To minimize any program to the System Tray (notification area) right-click the program’s Minimize button. To restore it, click the program’s icon in the notification area. To exit the app, right-click on any tray icon created by RBTray and click Exit RBTray in the popup menu. If you want it to automatically start after you reboot, create a shortcut to RBTray.exe in your Start Menu folder. It is quite a useful tool, and if you like it, you can download it from SourceForge. See this post if you want to minimize windows & programs to your desktop as Thumbnails instead of as Taskbar Icons.
