We have released the December security updates to provide additional protections against malicious attackers. As a best practice, we encourage customers to turn on automatic updates.
More information about this month’s security updates can be found in the Security Update Guide.
As a reminder, Windows 7 and Windows Server 2008 R2 will be out of extended support and no longer receiving updates as of January 14, 2020.
