Careful. "Restore Windows", if I understand your selection, has a different purpose.
When you quit any (well, any that has implemented this feature) application and then open it again, if "Restore Windows" is selected you will see the window that was last open.
For example, you type a short letter in Pages, print it, Quit. Open Pages again and that short letter will re-open. I find this annoying since many times I want a clean start, but if you are working on an on-going project, this could be helpful.
