The right pane of the Security and Maintenance window contains the Troubleshooting link. You can click this link in case any troubleshooting needs to be done in your PC.

The Recovery link on the window allows you to create or restore System Restore Points. From here you can also reset or refresh your PC back to the factory defaults, and start over if you have messed the things up. (Same as Recovery description (same window) as the point 6-f above).
