no, it's under the menu headings. Select Modeling from the pull down menu set on the left and then select polygons from the menu headings at the top. Create polygon tool is like the first or second choice. If you can't see the menu headings than hit ctrl and spacebar a few times until all of your menus and whatnot are visible. It's definitely there - it's not like your version is missing it.

but yeah, like happymat said: F1!
