I just bought a new laptop that came with two recovery disks on DVDR. I also have a desktop with Windows XP installed. Can I use the Vista operating system on the disks to update my desktop to run Vista? Ask if you need more details.

I understand this is possible with ubuntu installed first but I have windows 7 already installed. Is this possible?

I have an xp pro cd that I bought (not OEM – new in box from retail store) and installed on a computer I have. Now I want to install it on a different computer. How do I make the transition to switch the license to the new computer?
