I have 18 updates waiting to be installed: 9 of them important, one of them a service pack from 11/11/2008. It seems to be installing, going through the motions, but then comes back with the following error message codes --
Code 80070652 Windows Update encountered an unknown error.
Code 652 Windows Update encountered an unknown error.
I have tried to only install the important ones. I have tried to install only the service pack update. None of them work.

Any advice? Thanks, Cathy
