How to stop menus from loading above taskbar

I just installed TLB onto a newly built Windows 8.1 system, copying over the settings from the old PC. When I boot, however, a duplicate box with the menu shortcuts appears adjacent to the taskbar (it can slide along the taskbar border). As this is redundant, how do I keep it from starting every time I start Windows?

I can right mouse click on the edge of it and close it, but how do I keep it from starting?

Thanks for any assistance.
