Since the Registry is a cornerstone of the Windows Operating System, Windows automatically creates a partial backup upon successfully booting Windows. If you have issues booting Windows at another date, you can run Windows using the “Last Known Good Configuration” to automatically restore a portion of the Registry called the Control Set.
In any case, it’s still a good idea to create a full backup copy and store it on some type of removable media such as a USB thumb drive, a separate hard drive or optical media.
To create your backup, follow these steps:
- Go to Start, Programs, Accessories, System Tools, Backup.
- The Backup Wizard should start (Figure 1). Click Next.
- If the Backup Utility starts – without starting the Wizard as shown in Figure 2, click the link labeled “Wizard Mode”.
- On the Backup or Restore window, click “Backup files and settings”. Click Next.
- On the “What to backup” window, select “Let me choose what to back up” (Figure 3). Click Next.
- On the “Items you want to back up” windows, expand “My Computer” and select “System State” (Figure 4). Click Next.
- Select a location to save your backup to and click Next.
- The summary screen will display the settings you select. Click Finish to start the backup.
- The backup will begin. Note that depending on how many applications you have installed on your computer – or whether or not you’ve ever run a Registry cleaner, the backup may be quite large.
After a few minutes, the backup will be complete. Remember to keep your backups current - especially after any major application changes including installation and uninstalls.
