WinMetro is specially designed to bring the newly introduced Windows 8 Metro UI to Windows 7, Windows Vista and Windows XP. It offers an easy solution for old version Windows users to try and enjoy the tile based Metro UI. By displaying useful information such as weather, calendar, news, stocks, and frequently used programs, it turns your desktop into an informative and productive work station. It also offers the option to boot to Metro Start Screen directly.
In other words, you can enjoy the benefits of the Metro user interface even if you do not run Windows 8 – you still get the full-screen image viewer, the stock information or the weather forecast.
