Chinese Language Setings undetitable

[Guest]

The previous user on my PC used to be a Chinese that was so bad in English,
he set up all language settings to chinese. Now I can't get rid of them.
This is prevalent in
Windows XP,
Office 2003
Sophos Antivirus
Adobe Acrobat reader.
Funny enough, I un-installed all these programs and took pains to avoid
anything Asian upon re-installing, but still the fonts-(and
fontsize)selection in Office is still in chinese characters rathr than
Western characters, the sophos update has no western characters at all.
I cannot switch the ASian language off in Office for once. How can I do that?
Then, I have removed all languages in the language bar
(control panel -- language settings -- languages -- details) except English
(keyboard). After restarting, the Chinese is back.
I even turned off advanced text settings in the advanced bar.
If I go to
control panel -- language settings -- languages -- supplemental language
support, the 'install fiels for East Asian languages' button is checked but
gray - inactivated. I cannot uncheck that. How can that be? How can I
reactivate thet?
Would that help getting rid of the Chinese Language Setings.
Can anyone help me?
Thank you

How can I remove Mircospft Pinyin IME?
(that's one of the programs running in the background making everything
appear Chinese. I just can't find it in the control panel
