Windows CE USB flash drive program

Looking for a program to run off USB flash drive. installer should place an .exe in the startup folder of windows so that the program on USB runs during each machine power up. For test maybe have a counter file on USB starting at 10 which is decremented by 1 each time machine is powered on. As unique feature of program - if startup folder exe which runs entire time machine is running detects USB flash drive not present - it should uninstall itself automatically. This is part of a larger project as this is first stage of testing.
