After the installation of Windows 7 Service Pack 1 the system reboots, and before windows comes up the registry is updated. I get an Error C000009A applying update 128115 of 387921 (/Registry) .... error which stops the system from restarting. Is there any way to get the system to restart and complete the service pack installation. The only way I have been able to get around this error is to restore from the system restore point prior to the service pack, but I would like to apply SP1 if at all possible. ????
