I recommended you to use the Linux VPS server rather than windows VPS server because it gives you isolated environment. Some other differences are:
>Fewer modules on Linux VPS hosting require fewer resources required than windows VPS.
>Linux handles MySQL databases and PHP based programs perfectly.
>Increased level of flexibility.
