What is RTM? I've tried to install WindowsXP-SP2-2180-ENU-FINAL.exe, but it give me message that says "This Service Pack cannot be installed on top of the Windows XP Service Pack 2 build currently installed on your compuer. Cancel this installation process, uninstall your current Windows XP Service Pack 2 build, then re-install this Service Pack."
Which basically makes me think I'm SOL. How do you uninstall a service pack build? Is there no workaround?!! Am I doomed to having to format and reinstall?!! NOOO!!!!!
