Windows XP’s System Restore is a great feature for recovering your system after you’ve made a configuration change or installed software that your computer doesn’t seem to agree with.

Every 24 hours, or when you make a change to your system, Windows XP creates a new restore point. System Restore can use up to 12% of your hard disk space for restore points. If you need to free up disk space, you can delete the existing restore points using the Disk Cleanup utility.

  1. Click Start, point to All Programs | Accessories | System Tools and click Disk Cleanup.
  2. Click OK.
  3. From the Disk Cleanup dialog box, click the More Options tab.
  4. Click Yes to confirm your actions.
