Windows 7 on its website. All of the videos are hosted by Latika Kirtane -- Product Manager for Internet Explorer -- who, in around two minutes, goes over some of the simplest features of Windows 7. Some of the sexier topics covered are Windows Search, setting up a home network, and the joys of parental controls. There's nothing earth-shattering that we didn't already know covered here, but you'll still probably want to check out the videos after the break, and hit the read link for all four.
