Purpose: RBTray is a small background Windows program that minimizes windows to the system tray.
Minimize options: Windows can be minimized to the tray by right-clicking the minimize button, Shift-right-clicking the title bar, or pressing Control-Alt-Down.
Restore windows: A window can be restored by single-clicking its tray icon or selecting Restore Window from the icon’s right-click menu.
Compatibility limit: Some windows cannot be minimized properly, including Windows Store application windows such as WhatsApp.
Mouse hook option: The --no-hook option avoids the mouse event hook and leaves Control-Alt-Down as the only minimize method.
Hook dependency: RBHook.dll is only needed to support the mouse event hook and is not needed when using --no-hook.
Exit: RBTray can be exited from a tray icon’s popup menu or by running RBTray.exe with the --exit parameter.
License and price: RBTray is free and open source under the GNU General Public Licence.
Downloads: The project provides 32-bit and 64-bit binaries for download.
Startup: To start RBTray automatically after reboot, the instructions say to add a shortcut to the Windows Start menu Startup group.
Maintenance: The project is in maintenance mode: no new features are planned, though bugs may be fixed if reported.
Security: GitHub reports that the project has no SECURITY.md policy and no published security advisories.
Maker and origin: Benbuck Nason maintains this fork of RBTray, which originated from the SourceForge RBTray project.
