The user can manually create restore points, or System Restore can keep restore points automatically.
This is done without loss of personal files or data such as word processing documents, spreadsheets, music, images, etc. This feature is enabled by default and runs in the background making backups after certain events happen on your computer. System restore functions are only available to an administrator of the computer.
