Autosuggest includes search history

Autosuggest on Bing now supports query history. That means that if you are performing a search, autosuggest will show you previous search queries in the same color your browser uses to display visited links (purple). It even does so after you’ve typed a few characters!
This is handy if you search for the same topics again and again, e.g. your favorite hobbies.

What about privacy you say? Well, you are in full control of your query history. You can turn History on or off at any time or selectively remove any portion of your search history using the Manage History option. Both of these choices will be displayed every time you use Autosuggest as you can see in the screenshot.
