In Windows 7 and previous versions of Windows, one had to use third-party software in order to mount an ISO or IMG file. Luckily, both Windows 8 and Windows 10, support mounting ISO and IMG files out of the box, meaning you can now mount ISO and IMG files without having to install third-party applications.
Mounting an ISO or IMG file is extremely easy in Windows 10/8. You just need to right-click an ISO or IMG file, and then click Mount option to see the contents of the ISO or IMG file in File Explorer. To unmount the ISO or IMG, simply right-click on the mounted drive in This PC, and then click Eject button.
Although the Mount feature works without any issues, at times, you might not see the Mount option when you right-click on an ISO or IMG file. This happens, when the Windows Disc Image Burner is not the default program for ISO or IMG file types.
If the Mount option is missing from the context menu in Windows 10/8, complete the below mentioned directions to restore it back with ease. The procedure is the similar to the one we used to fix the Burn ISO option missing from context menu.
