How to download and install the August 2019 security updates

Home computer systems running Windows are configured to download and install updates automatically. It is recommended to wait with the installation of updates or create backups of the system before updates are installed; updates may introduce issues of their own on systems including major issues that may prevent PCs from booting into Windows.

You may run manual checks for updates to speed up the installation of the new updates

  1. Tap on the Windows-key, type Windows Update, and select the result.
  2. A click on "check for updates" runs a manual check. Updates may be installed automatically or on user request depending on system settings.

Another option that you have is to download the updates manually from the Microsoft Update Catalog website.
