Once in “System Restore”, you’ll have two options in the first window, the first is to restore your system to an earlier point. The second is to create a restore point. Choose one and then click “Next”.

If you clicked “Restore my computer to an earlier time”, you should see a calendar with the dates for you to restore to, and a description of what happened that day that you can restore to. Choose one, and click “Next”.
