Sometimes you may find that the HTTP URL shortcut icon is “broken”; referencing %SystemRoot%\system32\SHELL32.dll,0 instead of %SystemRoot%\system32\url.dll,0. This is due to a bug that does not consistently set the default type and data for the HKEY_CLASSES_ROOT\HTTP\DefaultIcon value. When the icons are not displaying correctly, it will have a default value of type REG_SZ with Data “%1″ when it should be of type REG_EXPAND_SZ with Data “%SystemRoot%\system32\url.dll,0″. Strangely, the DefaultIcon for the HTTPS (HKEY_CLASSES_ROOT\HTTPS\DefaultIcon) URL shortcut does not suffer from the same problem. I hope you find this information of value.











How to fix this?

Use a registry import…
