Avrdude used as pograming software in Windows clicks on Start button and type, cmd to activate command line window.
Type on command line: avrdude–C avrdude conf-c arduino –p m16u2-vvv-U flash:w:Arduino—DUE-usbserial.hex:i
Used cd (change directory) command in windows to navigate to the folder where ovrdude.exe, avrdude.conf and Arduino –DUE-usbserial are located. I just copied them into the same directory to avoid long links.
