Remove Xbox Profile

Remove your profile from the consoles hard drive and any other memory units so the only way to sign into it is re-download the profile. Also, as a further measure, while logged into your account on the xbox website, click "my account" top right corner, then
click "security family and forums" then click "xbox 360 profile protection". From there it will show all the consoles that have access to your account, click "require profile download" for each one. This makes it so its required for you to redownload and input
your info to redownload and sign back into your account on each console.

will this work for xbox one as wel?

If it's an online account (meaning it has an email attached and can sign into Live) you won't lose the account. Anything purchased on the account is tied to the account and can be redownloaded. The only thing you could lose are game saves unless you have them backed up or stored on the cloud.

If it's an offline account (no email attached, never signed into Live), then you would lose everything on the account unless you backed it up.

Your XBOX profile is saved online and can be deleted from your HD on your xbox and without your email and password no one can access it.

Thank you for taking the time to post this on the Xbox Forums. We understand that you are seeking to remove an Xbox profile associated with your daughters Microsoft account.

A Microsoft account is an amalgamation of different services [Windows, Office, Xbox, Outlook, etc.] so once you have used one of these services, it becomes a part of your account.

There is no way to disassociate these services from your account either.

If she was not the one that used her account for Xbox related services, its implied someone knows her info and used it for this service. It may have also been added unintentionally.

At this point, I would have to recommend that you
update the password on your Microsoft account in order for you to secure your account, and prevent any unauthorized purchase if your payment instrument is attached to your account.

I'm sorry about any confusion or turmoil this might have caused.
