Using Microsoft Windows System Restore
The Windows 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. Any changes that System
Restore makes to your computer are completely reversible.
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.
1 Click Start → Help and Support.
2 Type System Restore in the search field, then press .
NOTE:
The User Account Control window may appear. If you are an
administrator on the computer, click Continue; otherwise, contact your
administrator to continue the desired action.
3 Click Next and follow the remaining prompts on the screen.
In the event that System Restore did not resolve the issue, you may undo the
last system restore.
