Installing either the Security Update for Internet Explorer or the Security Monthly Quality Rollup installs the fixes that are 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 4047206, the November 2017 Security Only Quality Update, and the November 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 November 2017 (or a later month) is already installed.
