If you’ve been wondering where all the advertising for Windows Vista has disappeared to, look no further YouTube. Starting from last week, Microsoft has begun uploading a series of original short videos showcasing a combination of Windows Vista, Windows Live and Office 2007 experiences.

Unlike the $500 million heart-warming “Wow” campaign at the start of the year, this campaign focuses much more on functionality with realistic end-user scenarios and clear benefits on how using Windows Vista, Windows Live and Office can help get the job done. Perhaps this marks the beginning of the $300 million more Microsoft’s throwing into the Vista advertising pool.
