Moduł ten umożliwia zmianę ikony pliku exe, działa na wszystkich prawie execach 😉 krzaczy się tylko na specjalnie modyfikowanych plikach etc. Ikonke zmieniamy funkcją UpdateApplicationIcon, pierwszy parametr to sciezka do ikony, a drugi do pliku .exe Mam nadzieje, że komuś się to przyda. Zaznaczam ze kod nie jest mojego autorstwa. Autor: Filuu
