Well, I'm not Windozer but  M-n P 
calls  (ess-swv-PDF ..)
and that is defined in lisp/ess-swv.el,
and on line 173
has
	  (call-process "pdflatex" nil tex-buf 1 latex-filename))

where call-process is an Emacs-internal function
{  C-h f call-process     explains the arguments 
   (call-process program &optional infile buffer display &rest args)
    and more }
Could you try changing the 'display' argument to call-process,i.e.,
replace
	  (call-process "pdflatex" nil tex-buf 1 latex-filename))
by
	  (call-process "pdflatex" nil tex-buf nil latex-filename))

(and *remove* the ess-swv.elc file {or remake it})
and see if that helps under Windoze?

In general (i.e. under reasonable OS es) I'd still prefer to
*see* the pdflatex happening, i.e., keep display set to non-nil,
but we could set it to nil for Windows.
