Microsoft and other companies often distribute software as an ISO file, an exact copy of a DVD. In Windows 8 and Windows 10, you can easily work with these files without needing third-party software. Here's how to mount the ISO image so you can see the contents and burn it to a physical disc so you can install the software on any computer.
Mounting or opening an ISO file is as simple as double-clicking on it, thanks to Windows' built-in ISO-handling capabilities. In Windows 7 and earlier, you'd need to use a utility like Virtual Clone Drive to mount an ISO.
When you double-click on an ISO file in Windows 8 and above, however, it opens to show you the contents, just as if you were browsing a CD or DVD.
In fact, it shows up as a virtual DVD drive and is assigned a drive letter. You can open and copy individual files and folders from the ISO once it's mounted.
When you no longer need to work with the ISO, here's how to unmount it: Right-click on the drive and select Eject.
Creating a disc of the ISO contents, whether as a backup or to install the software on other computers, is a cinch too.
1. Insert a blank CD or DVD in your writable optical drive.
2. Right-click on the ISO file and select "Burn disk image."
3. Select "Verify disc after burning" to make sure the ISO was burned without any errors.
4. Click Burn.
That's it! Windows Disc Image Burner will do its thing and let you know when it's finished.
Windows 10 doesn't include any built-in way to create an ISO file from a DVD, but there are free utilities that will help you do this, such as open-source InfraRecorder.
