How to download and install the December 2019 security updates

Security updates are downloaded and installed automatically on most (Home) Windows systems. Windows runs checks for updates regularly to download and install security updates released by Microsoft.

Windows administrators may run manual checks for updates to speed up the process or download patches from the Microsoft Update Catalog website.

Note: we recommend that backups are created before updates are installed.

Do this to run a manual check for updates:

  1. Open the Start Menu of the Windows operating system, type Windows Update and select the result.
  2. Select check for updates in the application that opens. Updates may be installed automatically when they are found or offered by Windows; this depends on the operating system and version that is used, and update settings.
