When you update your Microsoft Windows XP-based computer to Windows XP Service Pack 1 (SP1), some pre-SP1 hotfixes that were installed on your computer may not successfully migrate from the release version of Windows XP to Windows XP SP1.

  • When you install a Windows XP pre-SP1 hotfix on a Windows XP-based computer, an SP1 version of that hotfix is also copied to the computer for use when you update the computer to Windows XP SP1. When you update the computer to Windows XP SP1, the SP1 version of the hotfix is automatically installed.

  • After you update your computer to Windows XP SP1, some pre-SP1 hotfixes cannot be installed. You may receive the following error message:
