Using System Restore
Windows XP provides a System Restore feature that allows you to return your computer to an earlier operating state if changes to the computer's hardware
or software (including new hardware or program installations), or other system settings, have left the computer in an undesirable operating state. You can
also undo the last System Restore.
System Restore automatically creates system checkpoints. You can also manually create your own checkpoints by creating Restore Points. To limit the amount
of hard disk space used, older restore points will be automatically purged.
If your computer experiences an operating system problem, you can use System Restore from Safe Mode or Normal Mode to return your computer to an earlier
operating state.
System Restore does not cause you to lose personal files stored in the My Documents folder, data files, or e-mail messages after restoring the computer to an
earlier time. If you restore the computer to a point before you installed a program, the program's data files won't be lost, but you will have to reinstall the
actual program again.
System Restore is enabled on your new computer. However, if you reinstall Windows XP with less than 200 MB of free hard-disk space available, System
Restore is automatically disabled. To see if System Restore is enabled:
1. Click the Start button, and then click Control Panel.
2. Click Performance and Maintenance.
3. Click System.
4. Click the System Restore tab.
5. Make sure that Turn off System Restore is unchecked.
Before proceeding with any System Restore function, Dell recommends that you thoroughly read Microsoft's information about using System Restore. To access
this information:
1. Click the Start button, point to All Programs—> Accessories—> System Tools, and then click System Restore.
2. Click Help in the upper-right corner of the Welcome to System Restore screen.

Using the XP System Restore Wizard
In Windows XP, you can manually create restore points or you can use the System Restore Wizard to create the restore points for you. To use the System
Restore Wizard, click the Start button, click Help and Support, click System Restore, and then follow the instructions on the screen. You can also create and
name a restore point if you are logged on as the computer administrator or a user with administrator rights.
Manually Creating the Restore Points

The present date and time are automatically added to your restore point.

Restoring the Computer to an Earlier Operating State

1. Click the Start button, point to All Programs—> Accessories—> System Tools, and then click System Restore.
NOTICE: It is important to make regular backups of your data files. System Restore does not monitor changes to or recover your data files. If the
original data on the hard disk is accidentally erased or overwritten, or becomes inaccessible because of a hard disk malfunction, you will need your
backup files to recover the lost or damaged data.
NOTICE: Before restoring the computer to an earlier time, save and close all open files and close all open programs. Do not alter, open, or delete any
files or programs until the system restoration is complete.
