I am in college right now and I was stuck with a roomate that I dislike (go figure). Anyway when I leave to go to class, I think my roomate gets on my computer, even though he has his own. Everytime I ask him if he has, the of course denies it. I don't want to resort to putting a keylogger on my own box, but I would like to find out if he is using my computer.
My question is how can I make a program that counts everytime my computer is turned on (when i leave i turn my computer off). I assume that everytime I turn my computer on there could be a value that increments by 1, but I dont want this program to be detected. Any suggestions would be greatly appreciated.
P.S. I know the very basics of C++ so I'm not completely new with programming.
Thanks again
