My HP computer came with Windows 98se installed. Later I upgraded it to Win XP and have downloaded all the updates including service pack2. These days the computer is running very slow and since I have a new computer, I would like to dump most of the stuff on it and reinstall windows. The problem is that when I put the disk in, I get the message that the version on the computer is newer and it won't continue. I noticed that on the add-remove programs in control panel lists the service pack. Should I remove the service pack and try to reinstall widows or is there a better way?
