-1: The page you linked to helps you register new URL protocols, but it uses a completely different registry location than the one you mention. (HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\URL\Prefixes does not help you register new URL protocols. It helps Windows automatically add the protocol if you type an address without one. For example, if you enter, Windows will go to ftp:// ) You or someone with editing abilities may consider editing the answer. – Bavi_H Mar 27 '10 at 2:49
