Falls Windows mit deaktiviertem Numlock / Ziffern Feld startet, kann dieses Registry File helfen:

numlock.reg

Windows Registry Editor Version 5.00
 
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment]
"NUMLOCK"="ON"
 
[HKEY_USERS\.DEFAULT\Control Panel\Keyboard]
"InitialKeyboardIndicators"="2"
 
[HKEY_CURRENT_USER\Control Panel\Keyboard]
"InitialKeyboardIndicators"="2"
