In Win Vista 64-bit, the desktop Internet Explorer icon has disappeared. I
would like it back, and not as a shortcut, but the way it was. I have browsed
for a solution, and many suggest this:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\HideDesktopIcons\NewStartPanel

4. In the right hand pane, double-click
{871C5380-42A0-1069-A2EA-08002B30309D} key.
5. Enter dword value as 0 to enable the Internet Explorer icon on the Desktop.

It does NOT work in my system

Help, please. Thank you.
