windows xp start up screen

How can I get rid of the records windows xp has of email accounts and how many new messages they had at one point that appear on the windows xp start up screen? There's 3 users, and two of them have these lists of people under the usernames that have signed in to hotmail accounts, so under the user names it says "181 email messages," etc.

 

To delete a user account
