If you use a public computer, your browsing history like web addresses you have visited, web pages and files forming those web pages are kept by web browsers you are using on seperate folders on that computer. That cached data has many benefits.
But what if the cached data is used to get and build a profile data about you or even your private data like files, images, passwords, etc are stolen. If you are anxious about your private data, you can prefer anonymous browsing. But anonymity on the web will only prevent you to be tracked by web servers or the publishers on the web.
But you have to clear all the footprints you have left behind manually. I mean the cached files, cookies, history entries, etc that are recorded by your web browser and by the OS itself.
To delete cookies, deleting personal data and deleting browsing history and such actions will take some time. And you may fail to clear all your personal data especially if you are working with a computer at public places and internet cafes. Private browsing is actually a must in public places and places where computers are shared by more than one user.
Use always private browsing where is possible especially at such common places. InPrivate Browsing mode in IE8 prevents the Internet Explorer from recording and storing data about your browsing session during the session is active. And someone using the same computer with you will not be able to see which sites and which pages you have visited and what files you have displayed during your private web browsing on the browser. When a web user starts an InPrivate Browsing session on IE8 and begins his private browse, the Internet Explorer will open a new window which will carry the private browsing session.
