AjStone writes: Earlier this month Microsoft posted an update to Windows Vista that is not automatically pushed through Windows Update. The update (KB938979) states "This is a performance update. Install this update to improve the performance of Windows Vista in certain scenarios." and "These issues have been reported by customers who are using the Error Reporting service or Microsoft Customer Support Services." There are seperate downloads for 32 and 64-bit Windows Vista installations. Seems like Microsoft is actually listening on the other end of the "Send Error Report" button.
