Your question is unclear. The blender icon for it's .exe file? Or all the icons within blender?

sorry, see added image. I would like to make some custom icons to add to this menu. Go to Use Pref/Development/Development: Icon Viewer. This is only some of the blender art assets.

Your suggestion is not the question I asked. Blender has a internal ICONS as seen by my attachment. Are they editable?
