Sorry,
I guess I need to be more specific.
As shown in the tutorial, there has never been a folder named "Cache". This is just the function of the various folders found inside the Stardock folder in the tutorial.
Therefore, any Stardock program that writes a cache has a folder bearing the program's name - i.e., DesktopX, ObjectDock, CursorXP.
Deleting the folder for the relevant program will remove the cached settings (or user preferences) and force the program to load with the default settings.
