SOLUTION
Step 1
Los usuarios de Windows ME y XP, antes de llevar a cabo cualquier exploración, deben comprobar que tienen desactivada la opción Restaurar sistema para permitir la exploración completa del equipo.
Step 2
Eliminar esta clave del Registro
Importante: si modifica el Registro de Windows incorrectamente, podría hacer que el sistema funcione mal de manera irreversible. Lleve a cabo este paso solo si sabe cómo hacerlo o si puede contar con ayuda de su administrador del sistema. De lo contrario, lea este artículo de Microsoft antes de modificar el Registro del equipo.
