/*
CDesktopFolder should create two file system folders internally, one representing the
user's desktop folder, and the other representing the common desktop folder. It should
also create a CRegFolder to represent the virtual items that exist only in the registry.
The CRegFolder is aggregated by the CDesktopFolder, and queries for the CLSID_IShellFolder,
CLSID_IShellFolder2, or CLSID_IShellIconOverlay interfaces prefer the CRegFolder
implementation.
The CDesktopFolderEnum class should create two enumerators, one for each of the file
system folders, and enumerate the contents of each folder. Since the CRegFolder
implementation of IShellFolder::EnumObjects enumerates the virtual items, the
CDesktopFolderEnum is only responsible for returning the physical items.
CDesktopFolderEnum is incorrect where it filters My Computer from the enumeration
if the new start menu is used. The CDesktopViewCallback is responsible for filtering
it from the view by handling the IncludeObject query to return S_FALSE. The enumerator
always shows My Computer.
