Restoring Your Operating System
You can restore your operating system in the following ways:
l Microsoft ® Windows ® XP System Restore returns your computer to an earlier operating state without affecting data files. Use System Restore as the
first solution for restoring your operating system and preserving data files.
l If you received an Operating System CD with your computer, you can use it to restore your operating system. However, using the Operating System CD
also deletes all data on the hard drive. Use the CD only if System Restore did not resolve your operating system problem.
Using Microsoft Windows XP System Restore
The Microsoft Windows XP operating system provides System Restore to allow you to return your computer to an earlier operating state (without affecting
data files) if changes to the hardware, software, or other system settings have left the computer in an undesirable operating state. See the Windows Help
and Support Center for information on using System Restore.
NOTE: The Drivers and Utilities CD is optional and may not ship with all computers.
NOTICE: Make regular backups of your data files. System Restore does not monitor your data files or recover them.
NOTE: The procedures in this document were written for the Windows default view, so they may not apply if you set your Dell™ computer to the
Windows Classic view.
