How do I promote my account to an adult account?

Changing the birthdate on you Microsoft account, will not promote your Xbox account to an adult. By design, once you enter a date of birth on your Xbox account, it is locked and you will have to wait till it progresses naturally to adult.

This is by design and stops children circumventing parental controls.

Hello JavierSedano!

To edit your child account(s), we need to change
the birthdate of that account or
create/add another adult in your family
account. To change the birthdate, you may find the instructions to this question by following the links below:

• Change the birthdate on your Microsoft account.
• Age verification for parental consent.

To add another adult to your family account, kindly refer to
Add a child account your family
under To add another adult your family.

Update us on how it goes.

Guys, what I just need it to promote my child account to adult. I have no idea on how to do this.

I'm fairly sure it is set to adult.

Although I cannot find anywhere either on my Xbox dashboard (Setting option, parental lock option, etc.) or my online account settings, options etc. that states that it is a child or adult account.

I found in the help section, steps on how to promote an account from child to adult but followed the steps and didn't see the promote option.
