Fix Mount ISO Option Missing in Windows 10

Windows 8.1 and Windows 10 can have the mount option of ISO files by default. You can just right-click any ISO file and select Mount from the context menu. Previously it was done using third-party software which would create additional virtual CD/DVD ROM drives in which the ISO files were inserted virtually. But now, Windows Explorer has the capability of creating a virtual DVD ROM and automatically inserting the ISO file.

Closing Words

Although there are other files formats available on the internet, such as DMG, but are not natively supported by Windows. Thankfully, ISO and IMG files are very commonly used, and thus Microsoft had decided to support these image files. For that reason, users can directly mount such images to their PCs and can use them, without any third-party applications.

  1. Thanks Mike. Sorry author. Article is useless for Windows 10.

  2. Option does not work 100% I can mount the .ISO after following “Mikes” correct steps.

    I can then install the software, but when I go to run it, even though the .iso is still mounted and in explorer/ This PC, the program says it cannot find the disc.

    So problem not fixed if MS can’t mount .ISO so the mounted .ISO can be found by the software that is installed from the mounted, and left mounted, .ISO.

    Need fix for that problem.

    PS. Damon tools and WinCDEmu both have same issue…

    Running Win 10 1903 Ent, 32 bit in VM to run old educational learning software.

  3. Why is every single solution to this in Google supplying this garbage incorrect info? Just wasted half an hour trying this crap before I found Mikes comments with the actual answer…

  4. This article is worthless doesn’t work at all.
    If you want to mount an ISO simply do this.
    right-click the iso, and select properties in the menu.

    Under Opens with, select Change to change the file association

    select Windows Explorer

    After that you will have the Mount Icon back
