if u want linux within windows, there is WINLINUX which executes just like a windows aplication and provides you linux platform.

You mean execute Linux from within Windows? I would think you'd want to do the opposite. If you run Linux from within Windows a virus can still destroy everything, including Linux, and are still limited by Microsoft's bloat and inefficiency. If you run Windows from within Linux then you have the benefit of Linux security and the fact that Windows applications actually run faster under Linux than Windows.
