You'll need to read Windows documentation.
The difference between Process and ProcessID is that one is the result
of a call to the GetCurrentProcess function, and the other is the
result of a call to the GetCurrentProcessID function.
Currently R has no way to get the list of MDI document windows. I
think the function you want is EnumChildWindows, but you might need to
use EnumWindows. I can't remember whether MDI documents are child
windows or top level windows.
If you do get all of this worked out nicely, contributions of patches
to R would be welcomed. The file where this function lives is
src/gnuwin32/extra.c.
