Hello Helene Thomas,
Because the Microsoft account was accidentally set up as a child account, resetting the new computer alone may not fix the loop.
Use Microsoft’s documented procedure for “I’m an adult, but Microsoft thinks I’m a child”:
How to change a birth date on a Microsoft account
You will need to complete parental consent using a separate adult Microsoft account, then correct the affected account’s birthdate. Restart the computer and sign in again afterward.
Only consider resetting the computer if the setup loop continues after the account information has been corrected.
