When using an ico file containing the full range of resolutions, the icon selected for the application for replacement is in very low resolution. In attachement there is a screenshot of the same .ico file used with resource hacker on the left for the shortcut and icon-changer for the test.exe file. When viewing in any other mode like small icons, list, details, content, the application icon switches back to its original icon as per screenshot below.
