the grunt is right... and i did log in as "Administrator" for my experiment. I already had the "welcome" screen disabled, so logging in was just like hitting ctrl+alt+del twice from the welcome screen.
Private files are kept PRIVATE. only the user with the UID that made the files/folders can access the files/folders
But i just had a brainstorm.... doesn't the linux kernel 2.6 have ntfs support? you might have a way to get the files by booting a boot-cd distro like knoppix or phlak
