Bueno bueno, navegando por el site de Windows Vista me he encontrado con una utilidad que te descargas y te hace un escaneo de tu PC para ver "si da la talla" y que versión de Vista es la que más te conviene. La utilidad se llama "Windows Vista™ Upgrade Advisor BETA", y lo podeis descargar de aquí.



Yo le he pasado el test, y activando todas las opciones, me va advirtiendo de lo siguiente:
