After taking a look at the listed processes in Window's TaskManager, I've noticed that there are some process that has a different extension other than .exe. I then opened the folder location of one of those processes and their extension is the same as they are shown in TaskManager. So, I was wondering how they do it. I just wanted to learn how its done.
I've tried renaming my application with a different extension and it didn't run.
Why am I seeking answers to this question? For security purposes.
