Re: windows xp installation help
Yes, you will be able to use your CD with his genuine key. During the setup when it asks you for the key, just put his in.
**IMPORTANT - If the disk you have isn't actually the Windows CD and is made by Dell, Gateway, HP, etc, then it probably won't ask you for a CD key and then you shouldn't use your CD for his computer because you will then both have this same key, which can cause problems.
