I recently found this procedure to work for a similar intractable problem.
On the Start/Run line enter: net stop wuauserv
Open Explorer and Delete these folders:
\WINDOWS\SoftwareDistribution\SelfUpdate
\WINDOWS\SoftwareDistribution\WebSetup
\WINDOWS\SoftwareDistribution\WuRedir
\WINDOWS\SoftwareDistribution\AuthCabs
\WINDOWS\SoftwareDistribution\DataStore
\WINDOWS\SoftwareDistribution\Download
On the Start/Run line enter: net start wuauserv
Restart the computer, being sure you log in with an account that has
full Administrator privileges. Then open one instance of IE and give
the Windows Update site another try.
