Can't set my home xbox

Even if someone has set their console as home with your account, you should be able to set your own Xbox as home, as console homes can be switched 5 times a year. Do you get any error when you try to. Because you have changed your account password, and
if you set your console as home, other person can not do that again as he can't login.

Ok, thanks for your answer, I will try that.

You would need to contact support to see if they can reset it for you. http://support.xbox.com/contact-us

Just update your address and your Microsoft account name and your Xbox region should be matched with your address. "This solution worked for many gamers"

you have 5 change in a year starting the first time you set you're home console if you used all you need to wait finish the year or try contact support.
