Iconview

Iconview is an application to view all the icons on your Windows computer, no exceptions.

This application can scan all the available icons in formats such as ICO, EXE, DLL, and ICL, and allow you to view them with no trouble.

Another advantage is that it doesn't require any installation, nor does it add any new entries to the registry, so you don't have to worry about that, either.

It doesn't modify any files outside its own directories, takes up practically no space on your hard drive, and runs super-quickly. In short: a fast, lightweight, and simple application.
