Important 

  • The fixes that are included in this Security Update for Internet Explorer 4092946 are also included in the April 2018 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.

  • 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 4092946), the April 2018 Security Only Quality Update and the April 2018 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 April 2018 (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.
