IE doesn't include what you want as an option, you'll have to "train"
IE to do what you want it to do.

Maximize Internet Explorer On Opening
"Problem: When Internet Explorer opens it can range in size anywhere
from that of a postage stamp to almost filling the screen..."
"Solution: The default behavior for Internet Explorer is to open at
the same size it was at the last time it was closed..."
" * Open a single Internet Explorer window to the smaller size.
* Drag the corners of the window until it completely fills the
screen. Do not use the maximize button to enlarge the window.
* Hold down the Ctrl key, keep it depressed, and using the mouse
click File and then Exit on the menu bar. Do not use the "X" in the
upper right corner to close the window.
* Internet Explorer should now open in a full window.
* If it still opens to a smaller size repeat the above instructions,
substituting the "Shift" key for the "Ctrl" key."
I was glad to find this for you. If you have any questions, please
