Usei a ferramenta "trocador de layout de teclado chinês" com sucesso. Você pode encontrar um link para download e instruções aqui: link
edit: vou citar como editar manualmente o registro:
Fire up Registry Editor (regedit.exe).
Navigate to[ HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Keyboard Layouts ]and export this key for backup purposes.
Locate the subkey that represents the locale of your keyboard. For example the French locale can be found in key 0000040c
Write down the value of the Layout File key of your chosen locale. For example, for the French locale it is KBDFR.DLL
Locate the Chinese locale you want to change. For example, for the Chinese (Simplified) locale look for a subkey that ends with 0804.
Change the value of the Layout File key of the Chinese locale with the value of the Layout File key you have written down in Step 4.
You can optionally change the value of the Layout Text key of the Chinese locale. For example you can change “Chinese (Simplified) - US Keyboard” into “Chinese (Simplified) – French Keyboard”.
Restart your computer and you are all set!
