How to download and install the October 2019 security updates

Note: we suggest that you create a full system backup before applying any updates; Microsoft's track record of releasing updates without known issues has not been the best lately and while most updates may install fine and without issues on most systems, a backup ensures that you can restore the previous version if you encounter any issues.

Windows Updates are pushed to home devices automatically. You can run a manual check for updates to speed up the process.

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.

Cumulative updates may also be downloaded from the Microsoft Update Catalog website to install them manually. Note that you need to make sure that a compatible Service Stack Update is installed on the device.
