Vista Ultimate to XP Pro Downgrade RRS feed

  • Question

  • I understand that I can downgrade Vista Ultimate to XP Pro. I have Xp Pro Media (OEM) withn a Product key. But here's my question. The key is currently in use on another PC I own. Can I use this key for the downgrade. Or do I have to buy another copy of XP Pro with key. And if I do have to buy a copy. Why would they call it a downgrade. Thank You!
