Thank you for your reply
I do understand the script since i read the ducky script carefully. I also executed every line in the script by myself, not by the USB. I found that, every step was executed smoothly, it just stuck for the command STRING mode con:cols=14 lines=1 after saving the notepad file (config-156e3.ps1) into C:\ . I understand the ducky script, but i admit that i'm not get so familiar with CMD command. All i know about those CMD command is create a notepad file > save to C:\ > then executed it by CMD. I will try to learn command CMD later. Now i just trying to understand what error here. And i think it's because of wrong ducky script
