TouchKeyboard not working in Kiosk Mode

Hello Rob,

Thank you for posting question on Microsoft Windows Forum!

Based on the issue description. This symptom with Windows 10 IoT LTSC probably because Kiosk mode (Assigned Access) suppresses the standard shell triggers that call TabTip.exe. If standard "Typing" settings are not working, the issue usually lies in how the shell handles focus events for Win32 vs. UWP applications.

Since the potential reason for this failure is that the system does not detect a "lack of hardware keyboard" correctly within the restricted shell. You can consider to use Group Policy by navigating to Computer Configuration → Administrative Templates → Windows Components → Tablet PC → Accessories. Enable Turn on the Tablet PC Input Panel.

Another point worth mentioning here is that if using ShellLauncher, you can configure the kiosk shell to explicitly launch TabTip.exe (the touch keyboard executable) at startup. Here is the path C:\Program Files\Common Files\Microsoft Shared\ink\TabTip.exe
