Create a USB image that will automatically capture network traffic silently using wireshark

I am a network security student and am trying to do a proof-of-concept for quick, silent, and automatic network sniffing via a usb flashdrive. I want to be able to plug the flash drive in and have it automatically capture all network traffic on the lan for 10 minuets and silently save the capture to the flashdrive. There should be no popups or alerts on the screen. Looking for windows 7 support.
