Patch Management / Patch Tuesday

Things to Watch Out for in Microsoft’s October Security Patches

As Microsoft releases patches each month, there are known issues that the company communicates. Obviously, there are many more “issues” that arise due to the nature and limitations of patch testing, but at least there are known variables that companies can watch out for while testing and then delivering the security updates to the user population.

Here’s what to watch out for this month (so far)…

October 10, 2017—KB4041691 (OS Build 14393.1770) – After installing this update, downloading updates using express installation files may fail. After installing a delta update package, the KB numbers appear twice under Installed Updates. This issue doesn’t occur when you install a full update package. After installing KB4041691, package users may see an error dialog that indicates that an application exception has occurred when closing some applications. This can affect applications that use mshtml.dll to load web content. The failure only occurs when a process is already shutting down and will not impact application functionality.

October 10, 2017—KB4042895 (OS Build 10240.17643) – After installing KB4042895, package users may see an error dialog that indicates that an application exception has occurred when closing some applications. This can affect applications that use mshtml.dll to load web content. The failure only occurs when a process is already shutting down and will not impact application functionality.

October 10, 2017—KB4041676 (OS Build 15063.674) – Installing KB4034674 may change Czech and Arabic languages to English for Microsoft Edge and other applications. Systems with support enabled for USB Type-C Connector System Software Interface (UCSI) may experience a blue screen or stop responding with a black screen when a system shutdown is initiated.

October 10, 2017—KB4041681 (Monthly Rollup) – After installing KB4041681, package users may see an error dialog that indicates that an application exception has occurred when closing some applications. This can affect applications that use mshtml.dll to load web content. The failure only occurs when a process is already shutting down and will not impact application functionality.
