Thanks for your replies.
One more thing that i think you should know is that shortcut icons are showing correctly, i mean if i change icon of a program's shortcut then it will be shown correctly but in the properties menu, the icon appears as a black square.
I tried several times to rebuild icon cache. after downloading bat file and opening it and restarting windows, shortcut icons in properties was shown correctly but after restarting again the problem still exist.
