Como finalizar uma Handle de um Processo.exe no DELPHI

Delphi
Thread
Olá pessoal,

Estou parado a dias tentando resolver esse problema que é finalizar uma Handle do type [Mutant] e o Nome: \\BaseNamedObjects\\NetCfgWriteLock , 
alguém para me ajudar nesse procedimento, preciso finalizar essa Handle sem que o processo.exe também termine.

Segue o exemplo dessa imagem;

Agradeço a quem me ajudar;

¿Te refieres a cerrar el ejecutable?
No he entendido muy bien lo que necesitas.
¿Te da algún error?

[DarkSton]

Me refiero a la función de hacer clic derecho y close handle en la parte baja de la imagen donde dice files. E:/delphi7/panel GB retzu
Cerrar el ejecutable si sé.

[Neftali [Germán.Estévez]]

Aquí tienes un hilo en el foro que utiliza la API de Windows CloseHandle, que creo que es la que necesitas:
