Resets the virtual drive's icon back to default by deselecting the active overlay icon.
This method deselects the overlay icon currently in use, thus resetting the virtual drive's icon back to its default state (i.e., displayed without any overlay icons).
The Helper DLL must be installed in order for this method to function correctly. Applications can check to see whether the Helper DLL is installed using the GetModuleVersion method, and install it using the Install method if necessary.
Note: This method can only be called after creating a virtual drive, and cannot be called within events.
This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)
