It's been a while since I had to configure one of them but, login to the device as an admin and disable the write filters. There's an EasyShell configuration utility either in the Start Menu or Control Panel and there'll be an option to disable to toolbar. Don't forget to re-enable the write filters. 

Thing is we dont enable any tool bars during image creation. And write filters are enabled. So Im puzzled as to where its coming from....Im suspecting a hot key but damned if I know what :D
