Internet Explorer 8 InPrivate Browsing (incognito mode):
When checking email at an Internet cafe or shopping for a gift on a family PC, you don't want to leave any trace of specific web browsing activity. InPrivate Browsing in Internet Explorer 8 helps prevent your browsing history, temporary Internet files, form data, cookies, and usernames and passwords from being retained by the browser, leaving no evidence of your browsing history or search history.
You can start InPrivate Browsing by opening a new tab and selecting Browse with InPrivate or selecting it from the Tools menu. Internet Explorer 8 will launch a new browser session that won't record any information, including searches or webpage visits.
