A:AnswerIf you use the default browser, which is Edge, Bing will be the default search engine. You can change it to any one your want: Google, Amazon, DuckDuckGo, etc. There are 1,500 easily available search engines, and a virtually unlimited number if you search. Of course, you will need more RAM as you add engines, and I don't know if this computer will sustain that.
