IMGBURN is free and is for Windows and I use it to burn Debian CDs without any problem whatsoever. You could also use the Windows port of cdrecord as well.
Hello, I'm Sergio Tognarelli. I was downloading the netinst installer and during the download I read about methods for burning ISO images using Windows as OS. There aren't free software in the list of all the suggested software. So I would
propose you to add "Infrarecorder" (official page:
http://infrarecorder.org/) among the other software.
