Ya came to know:)
Actually i double clicked the killresp.exe file and saw in the task manager and the application was running and i once ended the process it got deleted and again came back and was visible.
This shows its only stops when the system shut downs right?
But i have to double click it every time the system is started.
i want it to automatically get executed when the system is booted.
And also after adding the path to the windows registry should i restart the system so that the system can execute the .exe file?
