Microsoft Defender AV must hide the Family options area.

Description

Discussion Text

The Family options section contains links to settings and further information for parents of a Windows PC. It is not intended for enterprise or business environments. This section can be hidden from users of the machine. This option can be useful if you do not want users in the organization to see or have access to this section.
