They come with the U3 software pre-installed. When you plug the device in for the first time, it comes up with a dialog box that asks you if you would like to activate the U3 capability. I chose not to activate U3 on both of my devices. When you don't activate U3 it leaves a program on the device that you can use to reactivate U3 later, if you want to. I erased the preinstalled software on one and reformatted the flash drive.
