ctfmon.exe is what runs the language bar. you can remove it by doing the following:
remove "alternate user input" in Office, by going to add/remove programs, and then select it and click "change"
when the setup pops up, choose "Add or Remove features"
then choose "choose advanced customization of applications"
then under Office Shared Features, make "alternate user Input" unavailable.
you'll need your office CD for some reason, but it will go through.
when it's done, go to control panel and "regional and Language options" then "languages" then "details"
remove everything except for:
- [default language]
...- Keyboard
........-US
then apply
After that, go to start, run and type this:
"Regsvr32.exe /u msimtf.dll"
without the quotes, and run it.
then go to start and run again, but type this:
"Regsvr32.exe /u Msctf.dll"
without the quotes, and run it.
then reboot.
