13 Security Bulletins were released – 6 Critical, 7 Important, and 0 Moderate

This Month In Brief

We have not uncovered any widespread problems with any of this month’s Security Bulletins and are releasing all of them.

Denied Non-Security Bulletin Updates: KB3123862 has been denied

MS16-009, MS16-011, MS16-012, MS16-013, MS16-015 and MS16-022 are rated Critical. After your next patch cycle completes you should follow up and make sure these are installed. Opinions vary on the order of importance but MS16-022, MS16-015 and MS16-009/MS16-011 should be your top priority.

No out-of-band security updates were released during the last month.

KB123862 – Updated capabilities to upgrade Windows 8.1 and Windows 7
https://support.microsoft.com/en-us/kb/3123862

No one is exactly sure what this patch does. Microsoft states “This update adds capabilities to some computers that lets users easily learn about Windows 10 or start an upgrade to Windows 10.” It seems unnervingly similar to last year’s KB3035583 which was an attempt to push out Windows 10 upgrades. For this reason we have denied this optional update.

Notable news: As noted last month support for Windows 8 and older version of Internet Explorer ended on January 12th, 2016. Support for support .NET Framework 4.0, 4.5, and 4.51 also ended.
