I used to use the following code but I no longer use bzr or windows.

;;; re-define vc-bzr-sha1 to work in windows
(require 'vc-bzr)
(defun vc-bzr-sha1 (file)
  (let ((sha1-use-external nil))
      (set-buffer-multibyte nil)
      (insert-file-contents file)
      (sha1-region (point-min) (point-max)))))
