Think of Windows HANDLE like UNIX fd, but Windows HANDLE works for everything - not just sockets, files, pipes, and character devices. Process Y doesn't go away until all references to it, via HANDLE, have been closed. It may not be running. It may have an exit status available. It doesn't go away, though, until you are done with it, and everybody who has a reference to it does CloseHandle().
