Remove Pinyin Input Method Editor (MSPY2 IME)

I posted the same message in the category of Windows Xp,
however, I found it seems it should be in Office category.
I downloaded Pinyin Input Method Editor (MSPY2 IME) from
Microsoft download center to input Chinese characters.
However, the MSPY2 is very difficult to use, and always
appear on your screen, I cannot find any command on the
taks bar to turn it off. It always auto shift from
English to Chinese. If I use other programs like Studio
MX, it always auto turn to Chinese mode, which I don't
want. It gives me more grieve more than anything else, so
I decided to remove it from my computer. I followed the
instruction on the download web site, go to control
panel, remove the program, however, it still appears on
my screen, and my office program. My Word is under this
Chinese character setting, I cannot even use Times New
Romman, and keep auto shift from Ebglish to Chinese
whenever I use Studio MX. I cannot get rid of it. Can
anyone help me on this? What can I do to remove this
program totally?
I am using Windows Xp home eddition. Thanks!
