It's better to do stuff like that with `eval-after-load' instead of
`require' because then tex.el(c) will only be loaded when you open a
LaTeX file and not right at the start of your Emacs session.  Here is
what it could look like:

(eval-after-load "tex"
  '(setq TeX-command-list
         (append TeX-command-list
                 '(("ps2pdf" "ps2pdf && start \"\" %s.pdf"
                    'TeX-run-command nil t :help "Generate PDF file")))))

Look at the output of `start /?'.  It assumes that an argument in
double quotes is supposed to be used as title for the console window
to be opened.

Add a pair of double quotes in front of the file name (see above).
