Simplified Chinese IME for Windows XP Pro

> Hi all,
> I heard that Windows XP Pro can write the simplified Chinese via the Chinese
> Input Method Editor (IME). I have the following questions:
> 1) Where can I download the IME to my Windows XP Pro?
> 2) I saw that MSDN has the Chinese IME 3.0 for Windows CE and the Chinese
> IME 5.02 for Ofiice XP. I do not think the Chinese IME 3.0 is right for
> Windows XP Pro.
> I tried to install the Chinese IME 5.02 to my Windows XP Pro PC and got the
> message said the Chinese IME 5.02 is not for Windows XP Pro. I am completely
> lost now. Please help and tell me where I can get the right Chinese IME and
> what version it is.
> 3) If the Windows XP Pro has the necessary IME, how can I access and
> configurate it in my PC?
> Please help and advise.
> Thanks in advance,
> SHC
