Microsoft-Windows-Embedded-KeyboardFilterService
You can use KeyboardFilterService in to suppress undesirable key presses or key combinations. Normally, a customer can use certain Windows key combinations like Ctrl+Alt+Delete or Ctrl+Shift+Tab to alter the operation of a device by locking the screen or using Task Manager to close a running application. This may not be desirable if your device is intended for a dedicated purpose. However, you can use KeyboardFilterService to suppress any key press or key combination that causes an undesirable system behavior.
