Hi
Two things, one, I use a search program named Agent Ransack for my search software.
It's free and it can find anything.
Just let it search for anything you can't find and if it's there it will find it.

Hi,
Thank you for posting your issue in Microsoft Community.
I understand that you have difficulty in changing your primary mail account in Windows 8.
I will definitely assist you regarding this.
To change your primary mail account you have to change the log in account to the one which you want to set it as primary account.
You have to switch the log in account to Local user account. Then switch back to Microsoft account and provide the primary Email ID to that user account.
Follow these steps:
Step 1: Switch to local user account
Follow these steps to create a “Local User account”.
a.Press “Windows key +W”.
b.Type “users” without quotes in the search box.
c.Then select “Users” from the left panel.
d.You will get an option “Switch to a Local account” right below your user account name.
e.Select “Switch to a local account” option.
f.Enter the required details.
g.Then login to the local account and check how it works.
Step 2: Switch back to Microsoft account
Follow these steps to create a “Microsoft account”.
a.Press “Windows key +W”.
b.Type “users” without quotes in the search box.
c.Then select “Users” from the left panel.
d.Select “Switch to Microsoft account” right below your user account name.
e.Enter the required details (Primary Email ID).
f.Restart the computer and then try to login using new Primary account.

It seems like this would let you regain access to your daughters original Microsoft Account as long as you know the address and password. Even the address would probably do it since it would let you use the email to recover the password.
