The Control Panel, All Tasks, and similar items apparently resist all attempts to convert them to toolbar form. However, you can get something like it this way. Add the "Desktop" toolbar if it isn't already there (right-click taskbar > toolbars > desktop). It contains "Control Panel" which cascades to the menu-like groupings, or to "All Control Panel Items" which in turn cascades to each item, and some of them cascade even further. You just have to move the mouse and hover in three or four places to reach the item you want. Just about everything in your system can be reached from that Desktop toolbar, including Recycle Bin, Libraries, Network, your User folder, and all drives, plus everything on your Desktop. And every folder in it will cascade through whatever chains of subfolders it may have.
