Windows 8, Windows 8.1 and Windows 10 offer built-in ways of mounting ISO disc image files. Windows 7 and other older Windows versions lack built-in ISO mounters, meaning those users must use third-party tools to mount ISO files. For users of modern Windows versions, there are three methods of mounting ISO files. A user can double-click the file to mount the file, right-click then choose “mount,” or select the ISO image in File Explorer, then click mount under “Disc Image Tools.” Once the ISO image is mounted, the image will appear as a new drive. Users of Windows 7 and other old Windows versions are advised to choose a third-party tool developed by a trusted company.
