*.iso images allow you to burn a full copy of large pieces of content to a CD or DVD from a single file. You can download .iso images of Microsoft software from Microsoft DreamSpark or our other Microsoft Discount programs to burn to disk on your computer.
The instructions below follow the .iso image-burning process in Windows 7 at IT Computer Classrooms. The process is similar in earlier versions of Windows. Check the Help section of your operating system for more information.
After you have downloaded a program's installation file (*.iso format for a Windows-compatible program) to your Windows computer's hard drive, you can burn this *.iso file to a blank CD or DVD. You can use this disk to install the program on another computer, or have a backup installation disk in case you need to reinstall the program in the future.
Note: For *.iso files that are larger than 4.7 GB, you will need to use dual layer DVD. See About Recordable Media Types for more information about different types of recordable DVDs.
To burn an *.iso file to disk:
There are two types of recordable CDs and DVDs: CDs and DVDs labeled "R" can only be recorded on once, while those labeled "RW" allow you to write data to them once and then add more files later. You can also erase the data on CD-RW or DVD-RW disks entirely and re-use them, which you can't do with DVD/CD-Rs. You can use either kind in IT Computer Classrooms.
For dmg or *.iso files that are larger than 4.7 GB, you will need to use dual layer DVD.
