Start64!RBTray is a small Windows program that runs in the background and allows almost any window to be minimized to the system tray by right clicking its minimize button.

Installing: Extract the 32-bit or 64-bit binaries (depending on your OS) to a folder, e.g. C:\Program Files\RBTray.  Double click RBTray.exe to start it. If you want it to automatically start after you reboot, create a shortcut to RBTray.exe in your Start menu's Startup group.
