Important 
  • The fixes that are included in this Security Update for Internet Explorer 4040685 are also included in the October 2017 Security Monthly Quality Rollup. Installing either the Security Update for Internet Explorer or the Security Monthly Quality Rollup installs the fixes that are resolved in this update.
  • If you use update management processes other than Windows Update and you automatically approve all security updates classifications for deployment, this Security Update for Internet Explorer 4040685, the October 2017 Security Only Quality Update, and the October 2017 Security Monthly Quality Rollup are deployed. We recommend that you review your update deployment rules to make sure that the desired updates are deployed.
  • This Security Update for Internet Explorer is not applicable for installation on a computer where the Security Monthly Quality Rollup or the Preview of Monthly Quality Rollup from October 2017 (or a later month) is already installed. This is because those updates contain all fixes that are in this Security Update for Internet Explorer.

Known issues in this update

Symptoms Workaround
After installing KB4040685, Internet Explorer 11 package users may receive an error message that states that an application exception has occurred when some applications are closed. This can affect applications that use mshtml.dll to load web content. This problem occurs only when a process is already shutting down. It does not affect application functionality.  This issue is resolved in security update 4047206.

After installing this KB, Internet Explorer 11 users who use SQL Server Reporting Services (SSRS) may not be able to scroll through a drop-down menu by using the scroll bar.

Using the scroll wheel on a mouse works as expected. Additionally, this issue is applicable to only document mode 11. Therefore, trying to load the page by using document mode 10 may work around the issue.

To change the document mode in Internet Explorer 11:

  1. Select F12.
  2. Select the Emulation tab.
  3. In the Document mode menu, select 10. The page reloads in the new document mode.

Note F12 tools are available on any page that you are viewing in Internet Explorer. To access the tools, select F12. Or, select the tools button Tools button icon , and then select F12 Developer Tools.

Microsoft is working on a resolution and will provide an update in an upcoming release.
