Since some time, Robert Millan has been working at a tool to make the Debian GNU/Linux installation easier for Windows users[1]. His work has been integrated on Debian Installer daily images and now on Debian-CD (tool used to produce the Debian .iso images) and hence provinding a better user experience.

Up to now, the user would see a "MS-DOS Window"[2] while running Debian autorun to open the README.html existent inside of the CD. It was ugly and user would need to know how to use the CD-ROM to boot and maybe even know how to set the BIOS to allow it. It has improved a lot since it now instead loads a nice graphical application that loads the README (and uses translated versions if available) and minimize itself[3], the tool allows the user to reboot the system and use the Windows bootloader to load the installer without requiring any special knowledge from the user.
