How to download and install the September 2019 security updates

windows updates september 2019 microsoft

Most home systems receive updates automatically especially when they run Windows 10. Updates are not pushed in real-time to devices running Windows. Some administrators prefer to install security updates the moment they are released, others to wait to make sure that the updates don’t introduce any issues on the system.

Note: it is recommended that you back up the system partition before you install updates. Use programs like Paragon Backup & Recovery Free or Macrium Reflect for that.

Admins may check for updates manually to retrieve the released updates right away. Here is how that is done:

  • Open the Start Menu of the Windows operating system, type Windows Update and select the result.
  • 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.

Updates may also be downloaded from the Microsoft Update Catalog website.
