Really thanks for your reference, Brink.
I've known how to do it that way before. Maybe my question has been unclear. Yet, I wanna know how to do it through Registry.
Adding or removing input languages in Windows 7 is easy (many tutorials online). Yet, when it comes to the keyboard under the input languages, it is a nightmare. (no tutorial online...)
To my astonishment, it's so easy to do it in WinXP Registry (as said in my previous thread). But it gives me much a hard time in Windows 7 Registry. Can anyone here tell me where the registry key relating to adding keyboard under an input language is?
I'm afraid, I don't know where the registry setting is for this.
If this is what you mean below, then you should be able to just select Keyboard under a language, click on Add, then check the ones you want to add for that language. You can check Show More to see more options. Step 3 in tutorial.
