CDrivesFolder should create a CRegFolder to represent the virtual items that exist only in
the registry. The CRegFolder is aggregated by the CDrivesFolder.
The CDrivesFolderEnum class should enumerate only drives on the system. Since the CRegFolder
implementation of IShellFolder::EnumObjects enumerates the virtual items, the
CDrivesFolderEnum is only responsible for returning the physical items.
2. At least on my XP system, the drive pidls returned are of type PT_DRIVE1, not PT_DRIVE
3. The parsing name returned for my computer is incorrect. It should be "My Computer"
