Windows IoT Enterprise allows you to build fixed purpose devices such as ATM machines, point-of-sale terminals, medical devices, digital signs, or kiosks. Kiosk mode helps you create a dedicated and locked down user experience on these fixed purpose devices. Windows IoT Enterprise offers a set of different locked-down experiences for public or specialized use: assigned access single-app kiosks, assigned access multi-app kiosks, or shell launcher.
Assigned access would work if it was a UWP app on Windows Pro and Windows Enterprise.

Assigned Access is a Windows feature that you can use to configure a device as a kiosk or with a restricted user experience.
When you configure a kiosk experience, a single Universal Windows Platform (UWP) application or Microsoft Edge is executed in full screen, above the lock screen. Users can only use that application. If the kiosk app is closed, it automatically restarts. Practical examples include:
Thanks
