Each time you install a Windows XP update, the operating system takes a backup of the current system files. These backups are large data files located on your hard drive. They are used to restore the operating system to a previous service pack and allow you to uninstall the new update if system issues arise. After you update to Windows XP Service Pack 3 and the computer runs smoothly, you can delete these backup files on your machine to free up hard drive space.
