Problem with the searches on an blank tab of Microsoft Edge

Hi

In Windows 10 v1511, when I open a new blank tab in Microsoft Edge and I write on it any word and I press Enter, the browser tries to load the http://<searched_word> page rather than performing a search with the default search engine. Why?

Thanks

Bye

I had this, if its the same its a setting in IE that affects Edge, open IE and click the cog wheel at the top right and then select manage addons, make sure the following is ticked
