How can I register on friend's computer?

How can I register on friend's computer?  I used the computer of a friend during a visit in Oregon, about a month ago to sign into hotmail and my.msn.  Now, a month later and in another State, whenever I change cities on my.msn weather cited these time appear on his MSN page.  When she changes them, they change on my computer.    It seems that I am still connected to his computer.  I changed my password.  I sent him my new password and told connect me and disconnect me.  It still occurs.

How stop the system to make changes on your computer, when I want to only change them on mine?  I use only email my.msn and msn.com.   I do not sign a site of msn for something else, except to post such a request.  I don't use social media, conversation or msn photo program rooms, and I never have.

Thanks for any help.
