Help!!!! Default System UI Language had been overwritten

[Guest Ultra Kiasu]

Now my original English version of Windows XP operating system now

thinks it is a non-English, probably a Simplified Chinese version.

 

This happened after I installed a english version of Chinese 3rd-party

terminal service application accompanied with a terminal access device

(similar to nComputing's L110).

 

Now my Windows XP are still mostly English-based, but all the dialog

buttons are in Chinese.

My search in START button failed to work (complaining some files is

missing).

To resolve above, I need to use Windows Update, but it complaining

that my Windows setup language is of different language...

 

I really don't wish to re-install my entire PC with a fresh copy of

Windows XP.

 

Anyone know what in the system/files or registry had been changed to

make my system to behave so erratic?

 

Appreciate some help here...

 

THANKS...
