theres no such icon in windows!
if you want to make a programm having the internet explorer icon:
Right Click on the file you want to have the IE icon > Change Icon > Click on Search in the box that appears, and search for the Internet Explorer (eg if you have a shortcut to IE on your desktop, just Search for it in the Desktop, click it, select the IE that is on that box that appeared, then ok, then Aplly and voilla! (i hope you got it)
if you cant find the IE icon (ie.exe) on your desktop or you dont have a shortcut there, try to search for it in your winnt file
