Microsoft September 2017 Patch Day: issues overview

Microsoft released updates for all versions of Windows and other company products on the September 2017 Patch Day.

The company listed only three known issues related to updates that it released on that day. While that is better than no information at all, it appears that the updates have caused quite a large number of issues that users and administrators experience when they install or try to install these patches.

Günter Born collected extensive information on issues on his German blog. This article provides you with an overview of the issues and suggested fixes in English.

Microsoft Patch Day September 2017 Issues

windows security updates september 2017

The following issues have been reported. Note that most have not been confirmed by Microsoft.

Installation issues KB4038792 (Windows 8.1) and KB4038782 (Windows 10)

The monthly rollup KB4038792 for Windows 8.1 and Windows Server 2012 may not install, and throw the following error message instead:

BG_E_CONNECTION_CLOSED – The connection was prematurely closed.

Users who reported the issue were able to fix it by running Microsoft’s Update Troubleshooter for Windows 8.1. You can download the free tool from Microsoft directly.

The cumulative update KB4038782  for Windows 10 Version 1607 and Windows Server 2016 caused issues on some systems as well. Users reported that the installation would freeze, terminate, or throw the error 0x800706ba.

The error code translates to RPC_S_SERVER_UNAVAILABLE. Günter suggests to restart the Windows 10 system and try again, and to check firewall or security software which may interfere with the installation of the update.

Issues with KB4038788 for Windows 10

The cumulative update KB4038788 for Windows 10 Version 1703 is the cause for a number of issues. User reports suggest that some have issues installing the update, that Microsoft Edge crashes constantly after the update is installed, and that the update may introduce black screen issues and blue screen of death errors on top of all that.

There is no fix yet other than to roll back to the previous update (which in turn would mean that September 2017’s security patches are not installed on the device.

Other issues

These issues are reported by only a handful, or even fewer users.

  • KB4038792 blocks WSUS — According to the report, installation of the Security Monthly Quality Rollup update for Windows 8.1 and Windows Server 2012 R2, may block WSUS on Windows Server 2012 R2. Update checks don’t function anymore.
  • KB4038777 and Internet Explorer shortcuts — The report suggests that the update for Windows 7 SP1 and Windows Server 2008 R2 blocks Internet Explorer shortcuts from working correctly.
  • Network issues on Windows 8.1 — User reported that only public and private networks were shown after installation of an update (the update is not mentioned, but it is likely KB4038792). The fix was to disable TCP/IPv6 in the adapter configuration, and restart the affected system afterwards.
  • KB4011086 and KB4011089 Outlook display issues — The two updates cause language display issues in Outlook 2007 and Outlook 2010. Microsoft confirmed the issue and is investigating it.
  • KB4011089 disables VBScript print function in custom forms in Outlook 2010. See Woody’s report here.
