Microsoft has an Update Patch on its Windows Update site. I urge everybody to get the update asap. The flaw can only be exploited if someone sends you an email 'first' that entices you to click a URL link embedded within the email message. Once you click the link "then" it would be possible for a malicious person to take control of your PC by way of the security flaw within DirectX. Again, don't dilly dally. Get the Patch asap if at all possible.

Best regards,
Mike
