My .iso image files all used to hvae the "nti" logo as their ico, and be called a "NTI iso image file"; due to the installation of NTI software. However, after uninstalling, the icons have no logo; just a blank page with a windows-like screen inside (as happens for an unknown file format), and are still called an NTI image file. They are default to open with Alcohol 120%, and I would prefer them to take that logo, and simply be called a "ISO image file". How do I change this? Thanks
