Closing a Specific Instance of Windows Explorer

I'm having a problem trying to WM_CLOSE a Window Explorer process in that sending that message will then try to close the Windows Shell explorer process and prompt the user to shut down windows. This is not the intended behaviour and I was wondering how I could work around it?

How can I close individual explorer windows gracefully, without shutting down the whole PC at the same time? The goal is to have the same behaviour as if the user had clicked on the X button themselves.

EDIT: I've found that I'm able to get all the child windows of the explorer process but from that point I'm not sure how to identify which windows are the actual, user visible / interactable Explorer windows.

How are you getting the window? You can obtain handles with winapi calls by text so perhaps the desktop explorer has no caption. http://msdn.microsoft.com/en-us/library/windows/desktop/ms633499(v=vs.85).aspx Look at the lpWindowName parameter.

Also, and I am just guessing here, you might look at the relationship between the desktop explorer and the other explorer instances as far as how they are related to the hande returned by GetDesktopWindow() http://msdn.microsoft.com/en-us/library/windows/desktop/ms633504(v=vs.85).aspx
