    For over a month my updates all failed with the above
    error. I tried all the fixes in this forum without
    success. Then on a lark I tried to execute the update
    exe file. It of course failed but gave me more
    information than the normal update process provided. It
    said that "Cryptographic Services" must be running. I
    checked Services in msconfig and discovered
    that "Cryptographic Services" was not checked. I checked
    it to start it running and all my critical updates that
    have been piling up installed with no problem.

    Click on Start/Run, select or enter msconfig, click OK,
    click on the Services tab, and make sure
    the "Cryptographic Services" box is checked.
