Microsoft's Internet Explorer automatically fills in information through the AutoComplete function. This saves usernames, search criteria and even passwords, if you allow it. When you're on a public computer, or if you just want to keep you personal information private, turn off the AutoComplete function and remove stored usernames from Internet Explorer. Internet Explorer 6, 7 and 8 all have the AutoComplete function. Luckily, removing stored usernames and other stored information is the same for each browser.
