ok, first, open the ie...maximize the window, thenclose the window holding down the control key
now, right click on the ie icn on your desktop, hit properties, run, maximize
now hit the windows key+e, and make sure this window is maximized.
tools>folder options>view>save settings
now close this window while hollding down the control key.
do all of the above, and that should do the trick for everybody.
if it does not, you can try deleting these keys...make sure you do a backup
[HKEY_CURRENT_USER\Software\Microsoft\Windows\ShellNoRoam\BagMRU]
2:[HKEY_CURRENT_USER\Software\Microsoft\Windows\ShellNoRoam\Bags
and finally, if nothing else works, you can settle for this, which is not nearly as functional, but it might be good enough;
Start IE, right click any link on a web page, and select Open in a New Window.
Go back to the first IE window you opened and close it.
Return to the second window and manually drag it to fill the screen.
(Do not use the maximize button, for that's a temporary setting that will not be retained.)
Now press the Ctrl button, and close this second window, holding the Ctrl button depressed, using 'close' in the File menu (important!).
All windows should now open maximized
the first method I list will work for most users...try that first
