Cascading history

I have XP and can't figure out how to stop windows from
keeping a history of words I've typed in. For example
when entering text into box, windows comes up with words
that I've previously used, it wants me to highlight the
word then it will enter it into the box for me. Well this
list is getting huge and I want to stop it. I remember
upon set up at some point it asked me if I wanted this
feature, now I regret using it. Can anyone tell me how to
stop it???????

tools
internet options
content tab
autocomplete button
++++++++++++++++++++
clear these boxes.....as desired
[+] web addresses
[+] forms
[+] user names...
also press clear history button
++++++++++++++++++++++++++++++++++++++++++
