You need to right click each icon & in there somewhere will be properties & settings you should be able to find somewhere within those options that lets you stop the program loading at startup! Does that make sense?
After you have done that right click the tool bar & click 'PROPERTIES' then click 'CUSTOMIZE' when you click each icon/program it gives you 3 options just set it to hide always, when inactive etc depending on your preference!
