Windows 7 has an in-build feature to burn disk images. The process of burning ISO Images is very simple and easy to use.
1. For this example I am burning an ISO image to a DVD. So right click on the .ISO image and choose Burn disc image
2. This will open up the Windows Disc Image Burner dialog box where you can choose the CD or DVD drive and also check Verify disc after burning then click Burn button..
3. While the disc is being created there is a progress bar indicating how long until it is finished.
