Under Control Panel... System and security there is a link to 'Fix Problems with Windows Update'
I keep fixing, and after the fix, re-run, and the same issue is found.
Is there something to fix the fix?
I already installed (several times) the SP1 Rediness hotfix.
Hotfix for Windows (KB947821)
Installation date: 3/13/2011 10:09 AM
Installation status: Successful
Update type: Important
Fix for KB947821
Even after that, this troublshooting tool still detects (and says it fixes) the issue.
Is there something else to look at?
