The answer lies in the long tail of computing infrastructure. Tens of thousands of industrial CNC machines, medical devices, and point-of-sale terminals still run Windows XP or DOS. Recovery specialists need a reliable, offline, scriptable boot manager that does not phone home or require an internet connection.

For technicians who maintain old point-of-sale systems, industrial controllers, or retro-gaming PCs, remains the deployment tool of choice.
