In 2012, I have not been able to get that to work. I've always thought you had to remove the certificates in the registry in order to change the GUID.
If you look at the WMI class CCM_Client in root\ccm, you'll see two fields for GUID. One is PreviousClientID and the other is ClientID. If you delete smscfg.ini and restart the service, the field PreviousCLientID changes, but the field ClientID does not change. You can also look in the control panel and see the GUID not changing there.
