Nero has a demo version with limited capacities for free download, but it is no good for this job (doesn't offer the audio CD option at all, and if you press any advanced button a pop up window tells you to pay and upgrade. ) Windows 7 media player and burn tools do not recognize it without downloading some plug ins, so the only solution is free programs like this:

Please note that I have not tried this, I found it searching to solve the mystery. (I mainly use my Mac to burn audio CDs and Toast Titanium is fantastic! But when I used Nero in the PC, I remember that the full installation with updates and plug ins, was superb too. There is another path but it is a bit silly. Download CDEX, and transform the files into WAVs that are usually recognized by every CD burner. Hope that helps.
