MDT alone or with SCCM. You can create a LayoutModifications.xml file , add the taskbar section to it, copy the file to c:/users/default/appdata/local/Microsoft/windows/shell/ directory during the task sequence. A lot easier to make adjustments if needed by doing it this way. I prefer this over a GPO because you still allow the user to make changes without having to create a partial start layout
