System restore management

To delete one or several restore points, select the ones you want to delete from the list by ticking the corresponding checkmarks. Then click the Delete selected button, and confirm by clicking Yes. Even though the MSDN documentation says otherwise, this feature does not work for Windows Xp.

To create a new system restore point, click the Create new button. You'll be asked to enter the name for the restore point.

You can also enable/disable the System restore in this section. Just check/uncheck the Disable the system restore checkbox and confirm.
