The "taskbar" is the strip at the bottom of the computer screen with the "Start"button on the left. Also seen across the taskbar will be buttons for each application currently running on the computer. From the Start button, new applications can be opened such as screen capture and image editing programs. If the taskbar is not disabled, a clever fool may be tempted to hop from program to program trying to evade security precautions, which may ultimately result in system crash. The option of disabling the taskbar is inherited from earlier versions of CopySafe when it was not quite so  secure and remains as an option to save the embarrassment of would-be thieves.
Regardless of what method or application is used to copy CopySafe content, the result will not be a success.
