Problem:
Das Tastaturlayout bei der Anmeldung muß geändert werden

Lösung:

- Run Registry Editor (REGEDT32.exe).
- From the HKEY_USERS subtree, go to the following key: \.DEFAULT\Keyboard Layout\Preload
- Change the value for the following entry to contain the keyboard layout that you want to have avilable at logon.
This example would set the default keyboard layout to Japanese:\.DEFAULT\Keyboard Layout\Preload
"1" REG_SZ = "0411"

For Windows NT 4.0 and later, the following registry key tree contains a listing of keyboard layout codes:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layouts
