System Restore is a Microsoft Windows tool that helps you undo software changes to your computer without affecting your personal files, like documents,
photos, e-mails, 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 known good state.
Use system restore if changes to changes to the hardware, software, or other system settings have left your computer in an undesirable operating state.
NOTE: System restore does not backup your personal files and hence it cannot recover your personal files that are deleted or damaged.
