C:\Windows\System32\moricons.dll is still available, you can set them on shortcuts in Properties with the "Change icon" button.

Moricons.dll had icons for various DOS programs like word perfect.

The icons used in desktop are/were in progman.exe, shell32.dll and control.exe (IIRC, it was a long time ago).

What were the MS-DOS programs that Windows used the progman.exe stock icons for?

shell32.dll is unfortunately modernized on modern versions of Windows, with very few exceptions :( the Novell tree is still there.
