If you type Chinese, but also uses the Dvorak Keyboard Layout, how do you get the Chinese input system to use Dvorak layout? Here's the answer for Microsoft Windows (tested with Vista and 7).
Press 【❖ Win+r】 then type “regedit”. Then, go to the folder in this path:
That's the folder for Chinese simplified.
In the one named “Layout File”, change the value to “KBDDV.DLL”
Then, restart Windows. (relogin might also work.)
Here's the folder name for some other languages.
|Language||Folder Name||Original “Layout File” value|
Before you change, write down the original value, just in case you want to change it back.
