Toolbar items

[thisisreallymyusername]

Hello! 

I'm trying to remove these items from my Home toolbar, but they don't seem to be listed in the options. Does anyone know how I can disable all of these tools (in the red box below) that I don't even use?

Many thanks!

I believe the last four of those appear because of Add-in that have been installed on your computer. To remove the others, you would need to use the Office RibbonX Editor to modify the Ribbon.
