ISO 9660 is and older format required by older DVD/CD players. Windows doesn't clearly state how to burn this format.

  • There are many third-party tools to walk you through burning a CD or DVD in a number of formats, including ISO 9660. See thewindowsplanet.com/3025/… Jul 9, 2018 at 1:05
  • How is this an "unclear" question? This even states the ISO format, how clear do you want it?

Windows writes UDF format by default, but you can download an external program to write ISO 9660 format. This program does it if you select Data Disc, then Disc -> Format https://cdburnerxp.se
