Regional settings to english only still runs IMEs

When this computer was set up, supplemental language support was enabled in

regional options for right-to-left, script, and east asian languages. I

think that setting loaded IMJPMIG and two instances of TINTSETP.

Subsequently, those options were un-ticked and English is the only language

listed for text services. However, those three programs just mentioned

continue to load.

Am I safe removing them from registry run keys, or is it possible that

something else remains to be done in the switch back to English only which

would have removed these keys automatically?

Using XP SP3 Professional. This machine was previously on a domain and is

now a standalone.
