I don't believe so since Windows itself is looking in those specific locations for those settings. BTW what browser version are you using? IE 6 is the only version that I've seen that still requires the SocketSendBufferLength adjustment.
On Microsoft-based clients, one factor which can have an effect on performance is the send buffer in Internet Explorer6 and prior. the value for this can be modified using the technique outlined below. This has been resolved as of Internet Explorer 7.
