I'm not sure of the answer. Have you checked your system over with utility programs such as CCleaner for both Cleaner and Registry modes of cleaning?
Only options I see (Windows 8 only) are:
Control Panel\Appearance and Personalisation
Control Panel\Appearance and Personalisation\Personalisation\Colour and Appearance
Once in Control panel you can type in the word icon in the search bar to find various icon options. |
