Update FAQ

Why is security update 3161561 in this bulletin also denoted in MS16-075
Security update 3161561 is also denoted in MS16-075 for supported releases of Windows Server 2008, Windows Server 2008 R2, and Windows Server 2012 due to the way fixes for vulnerabilities affecting particular products are consolidated. Because bulletins are broken out by the vulnerabilities being addressed, not by the update package being released, it is possible for separate bulletins, each addressing distinctly different vulnerabilities, to list the same update package as the vehicle for providing their respective fixes. This is frequently the case with cumulative updates for products, such as Internet Explorer or Silverlight, where singular security updates address different security vulnerabilities in separate bulletins.



Note Users do not need to install identical security updates that ship with multiple bulletins more than once.
