What a wonderful tool within OS itself 😀 Just one-click away to explore the content of ISO image.
In Windows Server 2012 & Windows 8, we can explorer/read the content of ISO image by built-in option Mounting of ISO
This option does not need any 3rd party software like Magic disk/ISO etc.
Here are the steps for that. Go to ISO image> Right+click>choose Mount ISO option like below snap-shot.
Once you mounted ISO, image will be available as DVD drive then explore for the content like shown below.
