Performing Preinstallation Tasks

Before you install Service Pack 4, you should perform preinstallation tasks that will help ensure a successful installation. Performing preinstallation tasks will ensure that Windows NT and its services will run normally after Service Pack 4 is installed, and that you can uninstall the service pack if necessary and return the computer to its previous state. Good preparation includes a rollback plan, which includes updating the Emergency Repair Disk (ERD) and making a backup of the system files and the registry.

Before you begin the preparation, read the Service Pack 4 release notes, which contains instructions for installing the service pack and important information about the service pack.
