Important

  • Except for Internet Explorer 11 on Windows Server 2012, the fixes that are included in this Security Update for Internet Explorer (KB 4519974) are also included in the October 2019 Security Monthly Quality Rollup. Installing either the Security Update for Internet Explorer or the Security Monthly Quality Rollup installs the fixes that are in this update.

  • To obtain this update for Internet Explorer 11 on Server 2012, you must install this Security Update for Internet Explorer (KB 4519974). This update is not included in any Security Monthly Quality Rollup or Security Only Quality Update. For Internet Explorer 10 on Windows Server 2012, other called-out installation methods are applicable.

  • 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 (KB 4519974), the October 2019 Security Only Quality Update, and the October 2019 Security Monthly Quality Rollup are deployed. We recommend that you review your update deployment rules to make sure that the desired updates are deployed.

  • Except for Internet Explorer 11 on Windows Server 2012, this Security Update for Internet Explorer is not applicable for installation on a computer on which the Security Monthly Quality Rollup or the Preview of Monthly Quality Rollup from September 2019 (or a later month) is already installed. This is because those updates contain all the fixes that are in this security update for Internet Explorer.

  • If you install a language pack after you install this update, you must reinstall this update. Therefore, we recommend that you install any language packs that you need before you install this update. For more information, see Add language packs to Windows.
