Change from Child account to a adult account

Its not possible to change from an organizer (adult account) to a member (child account). Whether the account is an adult account or child account is dependent on the date of birth entered when the account was first created. The date of birth on the Xbox
account cannot be changed either.

Hey Xwarrior,

Did this account graduate naturally from a child account to an adult account or was there a birthday change attempt? You can change the birthdate to the Microsoft account but it will not change the birthdate that was entered originally to the Xbox profile.

In other words, a child account will remain a child account until it graduates naturally to an adult account. No way around it.

Can i change the status of my account from adult to child? And create a new adult account?

So, if I understand, you account is an child account and you want to unlink your parent's account from yours? Unfortunately, child account are not allowed to be managed without and adult account attached, you can ask yours parent's (adult account owner)
to contact support and ask for a change of adult account, re-alocating the child account to another MSA adult

You cannot change the account created as an adult account down to a child account. It needed to be created as a child account from the get go.
