RBTray

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
Shift-right-clicking its title bar
Using the Control-Alt-Down hotkey

Note that not all of these methods will work for every window, so please use whichever one works for your needs.

RBTray is free, open source, and is distributed under the terms of the GNU General Public Licence.

Download

Installing

Download either the 32-bit or 64-bit binaries (depending on your OS) to a folder, for example "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.

On Windows 10 that is located at "C:\Users\YOUR_USERNAME_HERE\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup"

But a much quicker way to access it is to press "WIN + R" then type (or copy & paste) shell:Startup

Using

To minimize a program to the system tray, you can use any of these methods:

Right-click with the mouse on the program's minimize button.
Hold down a Shift key while right-clicking on the program's title bar.
Pressing Control-Alt-Down on the keyboard (all at the same time).

This should create an icon for the window in the system tray. To restore the program's window, single-click the program's icon in the tray. Alternatively, you can right-click on the tray icon which will bring up a popup menu, then select Restore Window.

In some cases, the first two methods cause problems with other software because of they way they integrate into Windows using a hook to intercept mouse events. In these cases, you can use the --no-hook option, which means that only the last method of using the Control-Alt-Down hotkey will work. Also in this case the RBHook.dll isn't needed since it only exists to support the mouse event hook.
