I have a @hotmail.com address that was used to connect to my Windows 8 local user account. This is the account that shows up in the Users app, as well as on the lock screen.
I also have an aliased @outlook.com that I would like to use instead as the login name is nicer. Is it possible to change the app to use the alias instead? When I tried to log in during setup with the @outlook.com address it told me to use the master @hotmail.com address instead.
