How to I open an Incognito window / InPrivate window?

What is an Incognito or InPrivate Window?

Incognito mode is an Internet browser setting that prevents browsing history from being stored. Normally, when you visit any web page, any text, pictures, and cookies required by the page are stored locally on your computer. Additionally, any searches or forms that are filled out may be stored in autocomplete fields. Incognito mode forgets this data when you close the browser window, or doesn't store it at all.
