Windows 7: What files/folders keeps the Desktop Toolbars info ?

I have a consistent problem over time with my custom toolbars In Win 7 Pro 32bit. I have five custom toolbars :

Graphics
Design
Quick Links
Utilities
Browsers

If I change anything in the toolbars from time to time...the order functioning of the toolbars stays the same...but...the first item in the custom toolbar(s) will show a sliver of the icon and toolbar name...?...and it's started showing graphics on me again when I show the task bar.

If I have a system backup (Acronis ATIH2013) of a non-misbehaving start menu/desktop settingstaskbr...can I 'restore' the clean and clear Toolbars on the start menu/task bar with these previous settings ?

If so...what files from my complete backup of the system do I need to restore ?

Thanks...TRinAz

Figured this out by accident....seems small slivers/shadows of the icons in custom tool bars appear when "locking the Taskbar" because of changes in 'customization' of the main task bar displaying icons....if you add or delete program icons in "properties-customization"..it will throw the entire bar off and voila...slivers of icons showing when you 'lock the taskbar'...and the only way to correct is to delete and re-enter the custom toolbars.

Goto properties-customization and click 'show all taskbar icons' and my task bar at least self-corrected isntantly with no slivers of the programs showing thru.

May be more to it technically than that...but that solved my issues with this quirky annoyance when using custom toolbars & locking taskkbar
