Microsoft's Live Search is Microsoft's free Web search tool that plugs into various Microsoft Web properties as well as general indexing for pages all over the Internet.
Users can search for news stories, photos, videos, as well as Microsoft's other Web services like Live Maps and MSN. One thing that separates it from competitors is the Search and Give service, which takes 10 of your searches a day and converts it into charitable contributions to the nonprofit of your choice.
Besides Web searches, Microsoft has a few search tools built into Live.com that let you search books, XML feeds, and the company's questions and answers service.
