Currently gamesharing with someone and they have my account on their profile.. How do i get...

It was a rookie mistake on my part, was helping someones child out so they could play some games that he hasn't got. Is there no way that xbox/microsoft could help and disconnect my profile on their system?

You can't have an account on someone's profile. Do you mean it's on their console

Ultimately, you'll want to change your password. If you still have their console set as your Home, then set your own console as your Home (which is what it should be anyway).

If you change your password, it should ask him to enter the password before he could sign into your account. Since he won't know the password, he wouldn't be able to sign in. Otherwise, the only way to remove it is to physically remove it on their console. This is why it's against the rules to share account information with other people and why you should always sign out of your account after using someone else's console.

You can try contacting support, but to my knowledge they can't do that. http://support.xbox.com/contact-us

Yes sorry, on their console. I've got mine set as home but obviously with gamesharing, he can somehow still get on mine even with a password connected to my account?
