How to download and install the December 2020 security updates




Updates are already available via Windows Updates and other update management systems. Default Windows installations are configured to find and install updates automatically, but it is also possible to download updates manually to install them.

Tip: it is essential that you create a backup of the system before you install Windows updates as things may go wrong and backups help you restore the previous status quo.

You can check manually for updates in the following way:

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.
