Last month, we saw Microsoft serving up a fake Google Search box at the top of its Bing search results when ... especially when Microsoft has a documented history of this kind of behavior.

If you want to clear only a few searches just check the box beside the searches under ... it will again take you to the Search history page on Bing. Again, click on the Clear all button.

Microsoft seems to be testing a new related image search box in the main web search results in Bing Search. I personally cannot replicate this, which I take as a sign that this is a test.
