Getting rid of the Xbox app.

[WPCentral Question]

Did not realize that logging into the Xbox app and having it would alter the login procedures on my computer in general. Now every time I power on my computer it is under my email handle and requires my email password to login to the computer itself. Since I share this computer with my mother at this time, I do not want her having my email password, also I don't want logging in to the computer being anymore challenging than it was to begin with.
