Today, Microsoft released an updated version of the Approval Analyzer tool and updated the Knowledge Base article. http://support.microsoft.com/kb/912307.
The new version of the tool addresses an issue discovered last week where some updates not approved by the SUS administrator could be deployed. That issue only affected the original version of the Approval Analyzer tool. Therefore, Customers who have followed the manual steps in the KB need not take any action.
Customers who have not yet taken steps to address the issue discussed in KB 912307 or who ran the original version of the Approval Analyzer tool should download and run the new version of the tool.
