-- Backing Up the System State --
Backing up the System State includes the registry, the COM+ Class Registration Database, and boot files. Windows XP comes with Backup Utility accessible via [Start] [All Programs] [Accessories] [System Tools] [Backup]. In the Advanced Backup Wizard there is a setting to back up the System State either to one of the hard drives or a different media of your choosing. If the registry does become corrupt, the System State backup is used to restore the system.
The backup utility is not included in the initial install of XP, you have to add it from the disk yourself.In the Home Edition of XP as backup isn't installed by default. In the Professional Edition of XP the backup utility is already there.
-- System Restore --
The last method of backing up the registry is using System Restore, another utility that is included with Windows XP. System Restore is best likened to a camera taking a complete snapshot of your computer system at one point in time and storing that image in what is called a restore point. This restore point can then be recalled at some point in the future, effectively overwriting any changes that have been made to the computer since the restore point was created.
