XT9 Completely off

[alagares]

How can I turned xt9 completely off?
I always got to input settings and disable world completion but XT9 keeps coming up every time I use any keyboard.

XT9 its not useful at all for me b/c usually I type in two languages at the same time.

I tried this from htc forums but it really doesn't work in the touch as stated:

"Use Mobile Registry Editor to peform the following:
HKLM\SOFTWARE\Tegic\eT9\ and change the key "XT9SupportMSSip" from value "1" to "0". This will disable the XT9 for all keyboards except the Touch ones"
