Finally, Microsoft have incorporated ISO Image burning/writing to disc in Windows 7!
It’s also very easy to do.
On any .iso image you have, you can now right click on it and go to: Burn disc image.
You’ll then get a simple screen where you can select the burner, whether you want to run a verify afterwards, and that’s it!
If you want to mount the image without burning, then please check out: http://droptips.com/mount-an-iso-image-under-windows-7
