How to stop menus from loading above taskbar

I guess this is the standalone True Launch Bar. Usually to disable it you have to right click the empty space of toolbar and select "Close". This will close the toolbar and remove standalone TLB from the startup.

If this will not help (please let me know), right click the empty space of toolbar and select "Toolbar Properties". On the "Options" page turn off the option "Run on system startup". Press OK and close toolbar.

If this will not help, open the Task Manager, click "More details", select "Start-up" tab, find the item "Standalone True Launch Bar" and disable it.
