Windows 7 - How could I make the IE9 fill-up the full screen?

Hi
Just installed the IE9 in my 20inch screen. some of the web page at the bottom of the screen is out of sight!1
It has on the top of my screen about 1/2 an inch free space of the screen not utilised by the IE9!!. I have tried all the percentage 75% through to 125% with no sucess.
Has anybody got suggestion?

You could see from the window snip what I mean hopefully

Regards

press F11

Yes that has worked. Thank you.
On another note : I need to get use to the latest format!! When it fill the screen I loose the visibility of speaker,network connection details, & other icons. If I only know as to how to stretch the top part of this new IE9

Well...you could use the Auto-Hide feature of the TaskBar. Right click on the task bar, you will see Properties (at the very bottom), click on that, under Task Bar Appearance, select the second choice (Auto Hide Task bar).
