ISO Recorder
This is one of my favorite little Windows utilities. Install it and then right click over an .ISO file (that’s a CD disk image) that you would like to burn to CD. Your context menu will now have the option Copy Image to CD. Just click that, double check the settings in the dialog box, and go.
For some reason, at least on my laptop, whenever I need to use this program it has disappeared from my context menu, even though it is still installed, so I usually have to rerun the installer. For this reason, I would suggest keeping a copy of the installer around. Since it’s probably not a tool that you will use every day it can be a time saver, keeping you from having to dig it up online again if your menu loses its mind like mine does.
Please note that the author, Alex Feinman, has noticed a problem with it working on Windows XP SP2, so proceed with caution if you are running that operating system.
