VirtualBox SysTray LED

A native Win32 C++ system tray application (without a .NET runtime) that indicates the status of headless VirtualBox VMs using a tray LED (gray = none running, green = one or more active). The context menu lists running headless VMs with an option to shut them down, provides quick access to the VirtualBox Manager, and allows enabling or disabling autostart at login via the HKCU Run key.
