Restoring Your Operating System
System Restore
The Windows operating systems provide a System Restore option which allows 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. Any changes that System Restore makes to your computer are completely reversible.
CAUTION: 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.
