Microsoft's next operating system, Windows 7, has not got much dramatic visual changes and a departure from Vista. But then, M1 has a different purpose, it is not intended to provide eye candy. Vista probably has drawn more criticism than any other of the firm's OSs before. But, of course, it isn't quite what you would call a failure, since more than 100 million copies have been sold in a year or so.
Windows 7 M1 comes as a DVD image (2.7 GB in size). M1 version actually is not a standalone Windows version, but requires Vista as a foundation with Vista SP1.
