Windows 7 offers native support for burning .iso images. You no longer need to use 3rd party software.
To do so, right click on any .iso image. In its right click context menu you will see an option to Burn disc image.

Clicking on it will open the Windows Disc Image Burner.

This give you the option to burn the ISO image to CD or a DVD, and to verify the disc after burning it.
Click on Burn.
That’s it.
