Remove members : You can remove anyone that didn't need parental consent to join your family group. This includes organizers, members above statutory age, or member accounts in countries without parental consent requirements. To remove members without parental consent:

1. Go to family.microsoft.com.
   
2. Sign in with your Microsoft account.
   
3. On your family's page under the member's name, select More options > Remove from family group, and confirm.
