[Periyo]

Ya encontre la solución al problema. Encontre una funcioncilla muy interesante, mas que una funcion es toda una unidad.

Aqui os la dejo.

Solo teneis que crear una unidad y meter todo este código. Despues es cuestión de llamar al procedimiento "procedure ExportKey ( RootKey : HKEY; Key : String;
FileName : String; Overwrite : Boolean );"

Mandando como paramatros: Root,Direcion de la clave,Direccion y nombre del archivo donde se hara la copia, true para que sobrescriba si ya existiera el archivo o falso para que no lo sobrescriba.
