IMHO, your d program cannot have direct control over a spawned 
process. However, I suggest a road map for you, although I am not 
sure if it works.

- I don't know if d has something like C's expect [1] library, 
but you will need a similar thing. Basically, It spawns processes 
and handles their stdout. Maybe you can just wrap libexpect in D.

- Assuming you have "expect" running in D, you can spawn 
"tasklist" [2] and somehow filter out (I recall that it can be 
done with expect using a struct like a regex on stdout) its 
stdout to determine the PID number [2] of the process that you 
want to kill at the end of the program.

- then, in your main:
void main(){

     scope(exit){ // maybe you should also be aware of 
scope(success) and scope(failure)
         killPlink(); // spawn another process: "Taskkill /PID 
26356 /F"
