Recovering System Information
Tools provided by the operating system and PC Recovery 
software are designed to help you with the following tasks for 
safeguarding your information and restoring it in case of a 
system failure:
■Backing up your information regularly to protect your 
important system files.
■Making a set of recovery discs (PC Recovery software 
feature). Recovery discs are used to start up (boot) your 
computer and restore the operating system and software 
programs to factory settings in case of system failure or 
instability.
■Creating system restore points (operating system feature). 
System restore points allow you to reverse undesirable 
changes to your computer by restoring the computer to an 
earlier state.
■Recovering a program or driver (PC Recovery software 
feature). This feature helps you reinstall a program or driver 
without performing a full system recovery.
■Performing a full system recovery (PC Recovery software 
feature). With PC Recovery, you can recover your full 
factory image if you experience system failure or instability. 
PC Recovery works from a dedicated recovery partition on 
the hard drive or from recovery discs you create.

Maintenance and Service Guide B–3
Using System Restore Points
When you back up your system, you are creating a system restore 
point. A system restore point allows you to save and name a 
snapshot of your hard drive at a specific point in time. You can 
then recover back to that point if you want to reverse subsequent 
changes made to your system.
✎Recovering to an earlier restore point does not affect data files 
saved or e-mails created since the last restore point.
You also can create additional restore points to provide increased 
protection for your system files and settings.
When to Create Restore Points
■Before you add or extensively modify software or hardware.
■Periodically, whenever the system is performing optimally.
✎If you revert to a restore point and then change your mind, you 
can reverse the restoration.
Creating a System Restore Point
1. Select Start > Help and Support > System Restore.
The System Restore window opens.
2. Click Create a restore point, and then click Next.
3. Follow the on-screen instructions.
Restoring to a Previous Date and Time
To revert to a restore point (created at a previous date and time),

system and software programs to factory settings, in case of 
system failure or instability.

software allows the creation of only one set of recovery discs.

(purchased separately).

with the PC Recovery Disc Creator software.
■The computer must be connected to AC power during 
this process.

optical drive.

the disc creation process.

from the disc provided by the manufacturer or downloaded 
from the manufacturers Web site.
✎Before reinstalling the program, be sure it is fully uninstalled.
The Application and Driver Recovery tool replaces corrupted 
system files and reinstalls deleted system files within 
the program.
■In most cases, if the program you are reinstalling is still on 
your computer, the reinstallation process does not affect your 
personal settings.

computer, the reinstallation process reinstalls the program or 
utility to the factory image but cannot restore your 
personal settings.
