This question has been asked by countless people, and the Internet is filled with a wild array of answers.
If you bought an HP system many years ago, and it came with Windows XP, and you have the re-installation disc, if your system dies or needs to be recommissioned because it's unreliable, can't you use the re-installation disc to install the OS onto the new system? I've heard some limitations are involved but I don't know fact from fiction on these:
1. You can reinstall only IF you upgrade the system with the same motherboard because the key for the install is tied to the serial number of the motherboard.
2. You can reinstall only if you move the hard drive of the old system to the new one (which for me would be impossible because the old drive is IDE and the new one is SATA).
3. You can reinstall only if the new computer is a model from the same vendor (e.g., if you have the reinstall disc for a Dell computer it will only work in another Dell computer).
4. If you call MS customer support and explain that your system's motherboard has died they will "reactivate" the license for you on the new system.
5. You can't do it in any scenario because your EULA will state that you agreed to install the OS on the one computer and agreed it would not be used on another system.
Anybody have any definitive answers on this issue?
