- First off, a little maintenance: Right-click on the Start Orb, select Properties from the popup context menu, click on the Taskbar tab and de-select (uncheck) the Lock the taskbar option.
- Right-click on any empty spot of the Taskbar and select Toolbars → New Toolbars from the popup context menu.
- When the New Toolbar – Choose a folder window appears select "C:\ProgramData\Microsoft\Windows\Start Menu" as the directory to use for a Toolbar and click on the Select Folder button to choose it.
- After the new Start Menu toolbar has been made, drag it over all the way to the left until it is between the Start Orb and your pinned applications.
- Move your cursor over the separator bar beween the Start Menu toolbar and the and drag all the way to the left until all that is visible is the "Start Menu »" text. If you click on the "»" glyph you should now see a familiar menu tree.
- Right-click on the Start Menu text and select Open Folder from the popup context menu. The Start Menu directory will appear.
- Navigate to the Accessories directory, right-click on the Run shortcut and select Copy from the popup context menu.
- Navigate back to the Start Menu directory, right-click in any part of the empty window and select Paste from the popup context menu.
You should now have a "classic" Windows XP/Windows 2000 style Start Menu on your taskbar. Remember to lock the taskbar by toggling the Lock the taskbar option from the first step if you prefer a locked taskbar.
