Hello.... I just purchased a new computer, and it didn't come with a Windows XP CD, but it did come with the usual Recovery CDs that restore the system to its factory defaults. My concern is what would happen if I have to replace a major piece of hardware, say, the motherboard or hard drive. Does anyone have any experience doing this? Do the CDs still recognize that it is the machine I bought from the company, or would it deny the process because it thinks I'm trying to pirate the software? Also, what would I do if I had to install hardware and, as has sometimes happened to me before, I was prompted for the Windows XP installation CD? Thanks in advance if anyone has any experience with this.
