This bulletin summary lists security bulletins released for January 2017.

For information about how to receive automatic notifications whenever Microsoft security bulletins are issued, visit Microsoft Technical Security Notifications.

Microsoft also provides information to help customers prioritize monthly security updates with any non-security updates that are being released on the same day as the monthly security updates. Please see the section, Other Information.

Note: There are no security fixes or quality improvements for Windows 8.1 or Windows Server 2012 R2 for release on Update Tuesday for January 2017. As such, there is no Security Only Quality Update or Security Monthly Quality Rollup release for these platforms this month.
