The Microsoft Security Bulletin Advance Notification Service is provided to help users of Microsoft products plan for deployment of security updates, and includes information about the number of new security updates being released, the software affected, severity levels of vulnerabilities, and information about any detection tools relevant to the updates.
The advance notification bulletin also provides information about updated versions of the Microsoft Windows Malicious Software Removal Tool as well as non security, high priority updates on Microsoft Update, Windows Update, and Windows Server Update Services
The advance notification bulletin only provides information about non-security, high-priority updates that are released the same day as the security updates. The bulletin does not provide information about non security updates released on other days.
The bulletin is normally made available three business days before the regular security update release on the second Tuesday of the month. Upon release of the security updates, the bulletin advance notification is replaced by the security bulletin summary.
