Why are some of the keys on the physical keyboard not responsive in MetaDefender Kiosk?

MetaDefender Kiosk has a security requirement that the application be the only accessible item on the computer for non-administrator users.

As part of this security requirement, the system ignores certain keys on the keyboard that in Windows can be used in combination with other keys to close an application, access the desktop, access other programs, etc.

We have had requests from customers to enable these keys and our product team is researching ways to meet the security requirement while still providing the convenience of using the critical keys on the keyboard.
