Wrong keyboard layout at login screen

Here some updates on this case:
- the user has to set an input language (keyboard layout) for the preferred language in language settings. This setting will then be applied to the logon screen when he logs off, which is weird. Why a standard user can change the keyboard layout for the logon screen..?
- As soon as another user logs on to the machine, he has no keyboard layouts in the preferred languages and if he sets nothing and logs off, no Keyboard layouts are available and en-US is acitive.

It seems with the latest update Windows now takes the settings of current logged on user and applies them to login screen during log off. As long as no other user will log on, these settings will be kept for logon screen... hopefully this is not by design....
