What is it?
InPrivate Browsing is a way to browse the Internet anonymously. For example when checking e-mail at an Internet café, you may not 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 or search history.
How to enable it?
You can start InPrivate Browsing by opening a new tab and selecting Browse with InPrivate or selecting it from the Safety button on the top right corner of the browser window. Once you complete this action, Internet Explorer 8 will launch a new browser session that won’t record any information, including searches or webpage visits. To end your InPrivate Browsing session, simply close the browser window.
