You can accomplish this, but you will have to edit the Registry. This method was published by Stardock and is safe.
You can create string registry key to use Win32 menus on right-click on the taskbar to allow third-party extension of the menu.
Create a new String and name it S11_UseOldRightClickMenus and use the Data Value 1
Create this new String key in the following location:
HKEY_CURRENT_USER\SOFTWARE\Stardock\Start8\Start8.ini\Start8
As always, create a Restore Point or a Registry backup before changing the Registry.
You will need to restart your computer for this to rake effect.
