4000 m/cs took standard HD discs so there should be no problem physically reading them on a PC. Main problem is that the file extensions used by Canons (Txt, Inf etc) clash with Windows usage so unless care is taken, WP files auto-open in Notepad and appear as mostly garbage. With care, Word can produce a passable result but it is time consuming so easiest solution is a cheap professional conversion service - Google "Canon Starwriter Disc Conversion"
