I suppose that the Process Explorer use NtQuerySystemInformation with parameter SystemProcessInformation to get the list of processes. For the code example see my old answer . Additionally the function NtQueryInformationProcess will be used to get additional information.
NtQuerySystemInformation is only barely documented and "may be altered or unavailable in future versions of Windows" CreateToolhelp32Snapshot is fully documented and should give you the image name.
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.
