Microsoft has today released Bing Desktop Beta, the software is, predictably, a beta release of a desktop-based search tool that Microsoft is hoping will give people a reason to make the switch to its search engine, and leave Google behind once and for all.
Bing Desktop provides an automatic update of the Windows Desktop Background image to the Bing home page image each day. In addition, Bing Desktop offers an easily accessible yet unobstrusive search box to streamline searching without opening the browser.Download Bing Desktop Beta for Windows (Microsoft Link)
Note: Bing Desktop Beta does not run on Windows 8 Consumer Preview, not even in “Compatibility Mode” pointed towards “Windows 7”. Therefore, Windows 7 is a big compulsion if you want to install Bing Desktop Beta.
