Windows 10 IoT Core can be configured for either headed or headless mode.
A UI is provided. A single UI app will be launched at system boot and there can additionally be 0 or more “Background Apps” (StartupTasks).
There is no UI. The UI stack is disabled and UI apps will not launch. This reduces the amount of system resources used. If you attach a monitor to your device, the screen will be black.
