System hacks: Move the registry to let the system re-mount ISO

In Windows 10 File Explorer, by default, you can double-click an ISO file (or via the Load command in the context menu) to open the ISO file directly as a virtual CD-ROM drive, but sometimes we may encounter the situation that the double-click is invalid or the Open ISO file option in the context menu is missing. What can I do to solve this problem?

First, we need to clarify the reason for the above problem. Generally speaking, when we install a certain software that will be associated with ISO or modify the related services, it may block the system’s own ISO opening function. At this time, if you uninstall the relevant software or restore the relevant services, the system’s own function may be restored. In addition, some system updates may also cause this problem. If the above problem is not improved after blocking the recently installed software and services and the cause cannot be determined, we can fix the problem by modifying the registry.

Type “Registry Editor” in the search box of Windows 10 taskbar, and click “Registry Editor” in the search results automatically matched by the system to launch the Registry Editor application. Then, in the Registry Editor window, locate “HKEY_CLASSES_ROOT.isoOpenWithProgids”, double-click the “Windows.IsoFile IsoFile” string value in the right pane, and set its value data to empty (Figure 1).


Next, locate “HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionExplorerFileExts.iso”, right-click on the .iso branch and select the “Delete” option from the pop-up menu (Figure 2). Select the “Delete” option from the pop-up menu (Figure 2).


After performing the above operation, close the Registry Editor to complete the modification. After restarting the Windows system, the above ISO default functions will be restored.


If you find the above modification method troublesome, or worry about inadvertently changing the wrong registry, you can also directly download the REG script file (Figure 3) and run it to recover (script download address: , extraction code: rqcb).


In fact, in addition to using the functions that come with the system, we can also use the third-party software ImDisk Toolkit, which can be installed and built into the right-click menu command “Mount as ImDisk virtual disk” in File Explorer to open ISO files directly (Figure 4). Moreover, through the settings of the software, we can also directly edit the contents of the virtual disk and save the edited ISO image file.
