        This module takes advantage of a file privilege misconfiguration problem
        specifically against Windows MySQL servers. This module abuses the FILE
        privilege to write a payload to Microsoft's All Users Start Up directory
        which will execute every time a user logs in. The default All Users Start
        Up directory used by the module is Windows 7 friendly.
