System Restore
CAUTION: Backup data files regularly. System Restore does not
monitor or recover your data files.
System Restore is a Microsoft Windows tool that helps you undo software
changes to your computer without affecting your personal files like
documents, photos, emails, and so on.
Every time you install a software or device driver, your computer updates
Windows system files to support the new software or device. Sometimes,
this may cause some unexpected errors. System Restore helps you restore
the Windows system files to the state prior to the installation of the software
or device driver.
System restore creates and saves restore points at regular intervals. You
use these restore points (or create your own restore points) to restore your
computer’s system files to an earlier state.
Use system restore if changes to software, drivers or other system settings
have left your computer in an undesirable operating state.
NOTE: If newly installed hardware may be a cause, remove or
disconnect the hardware and try a system restore.
NOTE: System restore does not backup your personal files and hence it
cannot recover your personal files that are deleted or damaged.
