Restore ISO Association in Windows 8

The ISO file is a true image of an optical disk like CD, DVD or BRD. It can be used to emulate the CD/DVD in your PC without actually loading any optical disk in your CD/DVD drive. You can also use it to create an exact replica of the original disk by burning it on a blank CD, DVD or BRD. Windows 8 has native support for the ISO image files. You can double-click on an ISO image file to mount it in Windows and use it like a regular optical disk drive. But sometimes when you install third party software like WinRAR or PowerISO, they associate themselves with the ISO extension files and you can no longer use Windows to open ISO files. If you want, then you can restore this ISO image file association back to Windows Explorer. Here is how :
