The role of WINDOWS8 system protection

System protection is the ability to periodically create and save information about computer system files and settings. System Protection also saves previous versions of modified files. It saves these files in a restore point and creates them before a major system event, such as an installer or device driver, is occurring. Every seven days, if no restore points are created in the preceding seven days, restore points are created automatically, but restore points can be created manually at any time.

The drive on which Windows is installed will automatically turn on system protection. You can only turn on system protection for drives formatted with the NTFS file system.

　　There are two scenarios that can take advantage of system protection:

1. If your computer runs slowly or does not work correctly, you can use System Restore and restore points to restore your computer's system files and settings to an earlier point in time. For more information about System Restore, see System Restore: frequently asked questions.

2. If you accidentally modify or delete a file or folder, you can restore it to a previous version that is saved as part of a restore point. For more information about previous versions of files, see previous versions of files: frequently asked questions.

How to turn on system protection:
