My friend's keyboard and mouse on her computer just stopped working, as a result she bought a brand new one. I figured I could get it to work so She is giving it to me some time today. However, after I get it to work she is going to take the hard drive out. No big deal except doesn't that mean she will be taking the Windows operating system? It was a built from scratch computer so there is no reboot disk and I don't wanna pay a million dollars for windows. Is that a problem, will windows actually be gone? If so, what should I do?
