I deal with disc images semi-frequently, and one thing that I've found very helpful in the past is to be able to just right-click the ISO (or other format) image and select "Mount Disc Image" and it would automatically mount it as a virtual drive. Then I could view/copy the files I needed and then eject/unmount the drive and be on my way when I was finished.
I was under the impression that it had become a standard Windows 10 feature. But I've just noticed that I no longer have that context menu option, and I can't remember what utility I may have had installed in the past to enable it.
Does anyone have any ideas or suggestions on how to get this feature back?
