4 Security Bulletins were released – 1 Critical, 3 Important, and 0 Moderate

This Month In Brief

We have not uncovered any widespread problems with any of these patches and are releasing all of them.

MS17-003 is rated Critical. After your next patch cycle completes you should follow up and make sure this is installed. There is a known issue with the Windows 10 Edge patch – see below.
This is the lightest Patch Tuesday we can remember. There is no rollup for Windows 8.1 or Server 2012/2012R2

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

Heads Up: Known Issues with Windows 10 cumulative
The 3D rendering apps affects all 3 versions while the Cluster Service issue affects Windows 10 version 1607 only. There are not a lot of complaints posted about the 3D rendering apps so I do not think it affects a large number of machines. Unfortunately the only known workaround is to disable the additional monitor(s). The workaround for the Cluster Service issue is to manually start the service or reboot a second time.

KB3210720,KB3210721,KB3213986-Users may experience delayed or clipped screens while running 3D rendering apps (such as games) on systems with more than one monitor.

KB3213986-The Cluster Service may not start automatically on the first reboot after applying the update.
