I'm using my boss's microsoft office disc and since you can only use it on limited computers, (like microsoft office on 5 computers/laptop only) and i have to reboot (earse everything off the laptop) do you think if i reinstall Microsoft Office back into my laptop (the same laptop), you think it'll think that i use a differ laptop. Or would it know that it's the same laptop?

Most likely it'll think it's the same laptop because the licensing is usually tied to the hardware contained in your computer.
