Update
This tab deals with the Windows function called "Windows Update". If the option Activate automatic Windows updates is turned on and an Internet connection exists, Windows is allowed to connect to the Microsoft server to check whether updates for your system are available.
The option Notify before downloading updates can be activated if you want to be in control of your computer’s actions. As a result, Windows asks for your permission before downloading updates instead of silently downloading them in the background without asking for your permission.
