Admittedly this information is old, however I had to reinstall XP on a laptop recently and after updating it with SP3 and whatever other patch/fix I needed to install, the Language Bar appeared in the taskbar.
It’s a safe assumption to say the vast majority of Windows users have absolutely no use for this – myself included. So here’s how to get rid of it.
Go to the Control Panel.
Click the Regional and Language Options icon.
Click the Languages tab. You see this:
Click the Details button.
You see this:
Click the Language Bar button at the bottom.
You see this:
Uncheck Show the Language bar on the desktop.
And that’s it.
Im pretty sure last time I did this I simply right clicked on the language bar and told it to go away for same effect with a lot less clicks.
Not a permanent solution. It will keep coming back unless you dig into the Control Panel and remove it as outlined above.
