Lagging behind Google and Yahoo, MSN Search is the third-most-used Internet lookup tool. Microsoft hopes to catch up to its rivals, as it revamps and renames its search as Windows Live, dropping the MSN label. While MSN Search is still available, Microsoft plans to eventually merge and replace it with Windows Live. Public testing of the Windows Live beta becomes available at Live.com at 11 a.m. Pacific today. This set of tools adds image searching and allows you to build a sophisticated personal portal with RSS newsfeeds. Interface goodies include a nifty slider bar and scrolling, which aim to reduce the number of pages you click through when perusing search results. Check back soon today when we'll have a slide show highlighting the features.
