OK, an explorer process is always running, but it does not run
ShellDDEInit when it starts & it probably should.

I don't know if there is any desire for a native shell32 either. 
I think I agree with Dmitry that the built-in explorer should call ShellDDEInit. 
As it stands, for the built-in explorer, it is never called and the respective DDE interfaces are never registered.

ShellDDEInit is supposed to be called by the process that is acting as the shell (progman.exe, explorer.exe, etc) when it starts & begins handling the DDE interface for the shell.
The built-in explorer process should call this when it starts, so it starts handling the appropriate calls.
It should call ShellDDEInit(1) when it starts and ShellDDEInit(0) when
it terminates. I'm not familiar enough with the explorer code currently
to know where.
