The Microsoft Security Bulletin Advance Notification Service offers details about security updates approximately three business days before they are released. We do this to allow customers (especially IT professionals) to plan for effective deployment of security updates.

Advance Notification includes information about:

• The number of new security updates being released
• The software affected
• Severity levels of vulnerabilities
• Information about any detection tools relevant to the updates

For more information about the security updates that will be released on October 12, see Microsoft Security Bulletin Advance Notification for October 2010.
