I started playing around with the Orcas VPC and off course it uses the English keyboard layout. Now I needed to change it to Dutch (Belgian). Luckily I found here - How do I Configure the default keyboard layout during login .
Open registry and go to HKEY_USERS\.DEFAULT\Keyboard Layout\Preload . Change the value for the 1 key to 00000813.
Log off and check if it works - a complete list of the different keyboard layout codes is available at How do I Configure the default keyboard layout during login
