I run Windows Embedded Standard 7 with a multi touch screen (running on the UPDD driver 4.01.10). The system is running an application in kiosk mode with no need for any other input device.
The On Screen Keyboard is disabled in the Ease of Access center (and is not shown initially), but whenever a user touches the screen, a kind of "On Screen Keyboard Quickstart Button" appears at the left side of the screen, looking like this:

The user can use this to slide in the On Screen Keyboard. Is there a way to disable that?
