Hide a taskbar toolbar's text and title by default

I need to add toolbars which hides the shortcut/icon/application text and title as default.

I thought the best way would be through the registry (where everything like that can be set, but not this I guess).

To be more specific

Right click on taskbar -> Toolbars -> New...

When you first create a toolbar, the title and toolbar text is enabled by default. Then you would have to unlock the taskbar, rightclick inside the toolbar and untick show text and untick show title.

I need that setting automated and set to not show, through the registry or some other means.

Only thing documented I can find is taskbar settings located at HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Streams\Desktop

but everything is stored binary there, and I have a feeling if the option to hide text and label is in the registry it would be elsewhere.

Anyone can tell me if/where I can find this in the registry, or by some other means?

Taskbar is locked. Right-click the taskbar, uncheck "Lock Taskbar".

Then you will have the Text and Title options in the right-click menu for the toolbars.
