If you are using Windows 8 or 8.1, your have Internet Explorer 11 running as the default browser on your machine. IE 11 and Windows 8 use Microsoft Bing as the default search provider. Bing also suggest search results at the top. I found these search result annoying.
To disable these search suggestions, go to Tools and select Manage add-ons in your IE.
On the Manage Add-ons screen, select Search Providers in the left side listing. That will list all search providers installed on your machine.
Right click on Bing and click on Disable Suggestions.
This action will disable Bing search suggestions.
