I'm not sure if this is a operating system question, system administrator question, or a programming question. Let me explain what I want to do. I want a way to set up a program where I can run it and it have no chance of messing up anything in my computer. By anything I mean BIOS, hard disk (including info on HD), or any of my computer hardware. I don't really care if it crashes my comp, I just don't want any permanent damage.
Is there a way to do this? and no, I'm not trying to write virus's or anything malicous.
