hi, i made a really big mistake in changing icons, what i did was, i went to the my computer and opened the file options under tool and open the file types tab, i wanted to change the icon of the hard drive and the icon for the file folder, but then after i pressed the change icon button, and pressed ok, whenever i double click a folder or my hard disk it opens the search window, instead of opening the said folder, im currently in windows xp and i really need your help.. thanks in advance God bless..
