Icons on Windows 10
Usually, icons are stored in the “.ICO” file. Many Windows icons are displayed in the form of “application”, “folder”, “file”, “shortcut”, and there are many unique icons appropriate for each.
However, because it is impossible to store everything in the form of an “.ICO” file of image files, instead of saving and using icons in a “. DLL file” format as one.

Each icon has its own specific number that can be identified. For example, when editing registry information, specify the icon number to be used from Shell related registry information.
