Vista开始桌面可以用IShellWindows访问。
XP下桌面没有API，你可以查桌面上是不是有SysListView32 窗口，如果是的话，那么有大概率是桌面那个defview，这个在XP下item data是pidl，但是注意用户是可以自己用Active Desktop在桌面上放别的defview窗口的。

你这是自己创建了一个新的shell view（类似自己写了个资源管理器），你的代码对桌面并不会有影响，这是设计行为。

我在msdn上看 IShellFolder ：：CreateViewObject能创建系统的ishellview 是不是有什么条件我这种方法创建的还是对桌面没有什么影响
To support this request, create an object that exposes the interface indicated by riid and return a pointer to that interface.

The primary purpose of this method is to provide Windows Explorer with the folder object's folder view object. Windows Explorer requests a folder view object by setting riid to IID_IShellView. The folder view object displays the contents of the folder in the Windows Explorer folder view. The folder view object must be independent of the Shell folder object, because Windows Explorer may call this method more than once to create multiple folder view objects. A new view object must be created each time this method is called. Your folder object can respond in one of two ways to this request. It can:

Create a custom folder view object and return a pointer to its IShellView interface.
Create a system folder view object and return a pointer to its IShellView interface.
