I mean the classical Control Panel that's launched in Windows Explorer as opposed to the modern Settings app.

A shortcut, `.lnk`, can point to any object in the Shell namespace (a COM object) not only to objects on file system.

>From [the linked email](https://mail.openjdk.org/pipermail/awt-dev/2019-November/015494.html), I infer there's `The Internet` object (on a desktop? ) which is marked with `ATTRIB_BROWSABLE` but not `ATTRIB_FOLDER`. That is the Windows (File) Explorer can navigate to this object, yet JFileChooser can't because this object is not a file system object.

If I understand @mrserb's scenario where he reproduced the problem, one of the folders (Recent) contained a shortcut which has the same or similar properties: the File Explorer can navigate to the object to which the shortcut points, yet JFileChooser can't because it shows and navigates file system objects object.

A `.lnk` object is stable across Windows releases, basically it's a serialised form of `IShellLink` interface. Yet the shell would fail to resolve the `.lnk` if the shell extension it points to is not installed.
