How to download and install the February 2020 security updates

The security updates that Microsoft released on February 11, 2020 are made available via Windows Update, WSUS, and other updating tools and services. The updates may also be downloaded manually and installed just like any other application on Windows machines (check the section below for direct download links).

Note: Since Windows updates may introduce bugs or issues, it is highly recommended to create backups of important data — better the entire system — before running any updates.

To check for updates manually, do the following:

  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.
