After you upgrade a computer that uses a Japanese PS/2 Keyboard (106/109 Key) keyboard to Microsoft Windows XP or to Windows Vista, Device Manager indicates that the keyboard is a Standard 101/102-Key keyboard or a Microsoft Natural PS/2 keyboard. The keyboard functions as a 106 key keyboard but appears in Device Manager as a 101 key keyboard.
This issue occurs because Plug and Play cannot detect the type of a keyboard that a user manually installs. Therefore, almost all PS/2 keyboards appear in Device Manager as Standard 101/102-Key keyboards or as Microsoft Natural PS/2 keyboards.
To work around this issue, use the Keyboard item in Control Panel to reinstall the Japanese PS/2 Keyboard (106/109 Key) keyboard.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
