Like many of the annoying process and CPU-hogging Dell utilities, Answer Works (which also comes as "Answer Works 4.0 Runtime - English," for those using even older Dell laptops), doesn't really need to be on your PC.
What is AnswerWorks exactly? From what I've learned doing some quick research, AnswerWorks is a cross-lingual question answering engine that lets companies add a language interface to your PC's Help system, as well as knowledge databases on the Web. A user can type something in, and AnswerWorks offers suggested topics.
In other words, it's probably powering a lot of the Dell Help files. If you type in "i need help" in the search box it may also bring up related topics such as "support," "customer service," etc.
I'm not even sure that AnswerWorks is still used by contemporary software - so I've removed it. I haven't had any issues nor noticed a difference since the removal of "Answer Works 5.0 Runtime - English," but your experience may be different, so proceed at your own risk.
