You can also check and use the following regs in your personal OEM if you need to disalbe the auto complete or other things.
Code:
[HKEY_LOCAL_MACHINE\Software\Tegic\eT9]
"AutoAppend"=dword:00000001
"AutoSubstitution"=dword:00000001
"MultitapWordCompletion"=dword:00000001
"SpellCorrectionMode"=dword:00000001
There are others as well, but these should address the commonly reported complaints.
