Microsoft Security Bulletin Advance Notification

Security Bulletin Advance Notification

As part of the monthly security bulletin release cycle, Microsoft provides the Microsoft Security Bulletin Advance Notification Service. This advance notification is intended to help our customers plan for effective 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.

To help customers prioritize the monthly security updates with any non-security updates on Microsoft Update (MU), Windows Update (WU), and Windows Server Update Services (WSUS) being released the same day, the bulletin advance notification also provides information about:

Updated versions of the Microsoft Windows Malicious Software Removal Tool

Non-security, high-priority updates on Microsoft Update, Windows Update, and Windows Server Update Services

Note that the bulletin advance notification will only provide information about non-security, high-priority updates that are released the same day as the security updates. The bulletin advance notification does not provide information about non-security updates released on other days.

The bulletin advance notification 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, which is the definitive announcement of the security update release for the month.

Read the most recent advance notification or the most recent security bulletin summary.
