Microsoft posted for download a bunch of Windows XP Fun Packs and PowerToys that build on top of its Windows Media 9, Movie Maker, digital photography and browsing technologies. Among the more interesting of the downloadables is the Creativity Fun Pack, which includes a blogging plug-in for Windows Media Player 9 that lets users add information about their currently playing music to their Web logs. Microsoftie Sean Alexander blogs about the blog plug-in here.
