At Microsoft’s Professional Developers Conference 2008 (PDC 2008) in Los Angeles, Microsoft will distribute Windows 7 to participants of Steven Sinofsky‘s Keynote. This Pre-Beta of Windows 7 will obviously be distributed on a 160GB harddrive, which also contains conference notes.

Windows 7 will be based on Windows Vista and will be released in January 2008. Microsoft accentuated several times the support of multitouch displays. It will also contain the well known Office 2007 ribbon technology in WordPad and in Paint.
