I have used the Lenovo ThinkPad R61 (8920B6U) laptop and now there is a problem trying to downgrade to xp arrives on it. Initially it contains the preloaded with Windows XP Pro and comes with Vista Business upgrade CD and product key Operating System. Now when I try to upgrade the system with the XP conversion kit, then it won’t work to do this task. I hope many users will be doing the similar kind of task. Please help me to solve this issue.
