Advanced text services - ink correction

Out of blue it appeared two new keyboards in my language panel as you can see on this screenshot:

My operating system is Windows XP SP3. Whats weird this keyboard have been installed under all languages in my system (English & Slovak). What does it mean? Can I remove these new keyboards without any concern?

Solution 1:

It looks like this is a Windows feature that supports handwriting input devices. Have you connected one?

If you don't use handwriting detection devices, then it's probably safe to remove it, but this was probably installed because of a plug-n-play that was inserted with handwriting input.
