And it happened again. Somehow Internet Explorer kept opening in a teeny tiny little window instead of about 76% of the screen like I like it. And it didn't remember the size when I changed it for the next time.

So I went to Google again and it took five or so pages until I found the real solution. Not the "I think" or "try this" or "this should work".

Here is the way of doing it that I found works:

1. Close all Internet Explorer windows
2. Open one Internet Explorer instance
3. Take your mouse and (place and) size the window the way you want it
4. If you are running Vista and don't see the menu in Internet Explorer, press the "Alt" key
5. In the menu, click on "File"
6. Now put one finger on the "Ctrl" key and keep it there
7. Click on "Exit" in the File menu
8. Once Internet Explorer is closed, release the "Ctrl" key

That's it.
