Making an app/service such that trying to end/kill its process in Task Manager would result in “Unable to Terminate Process?

This is not achieved through code (well, it might be for critical Windows system processes, but you are probably not writing components of the operating system), but rather through access permissions.

I found that the function ProtectProcess() supplied in Prevent user process from being killed with "End Process" from Process Explorer results exactly in the effect I was looking for.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
