Because removing the shell-quote-argument call fixed it for me:
(when (eq system-type 'windows-nt)
(setq python-shell-exec-path '("C:/Python27"))
(add-function :override (symbol-function 'python-shell-calculate-command)
(lambda ()
(let ((exec-path (python-shell-calculate-exec-path)))
(format "%s %s"
(executable-find python-shell-interpreter)
python-shell-interpreter-args)))))
