Account settings in mail

Hi..
Am back with a good information i guess. Am not a good good gentle girl. I have often misused the enhancement options in mail accounts. For example, Internet Explorer has option to save passwords. this would help people with PC for home use as it eliminates typing username and passwords for log in. This option is hence available in college Labs and Internet centres as well.

Recently I made a mistake by clickin yes in save passwords dialogue box. This would enable auto complete in the username text box such that when we click on it it would promp the name which on selecting will complete the password textbox also.....

how to disable this??????
goto tools-> internet options
then click content tab..
-> auto complete..
-> username and password on forms(uncheck it..)
