The last state of a application window is saved by the OS automatically.
So, when you reopen Reader it will have the same windows size as the last time it was closed.
I have the same problem. Every first time when I open a pdf file, then Adobe reader does not open maximized. The next time I open the same document, Abode Reader opens it maximized or not maximized (depending on the state I closed this particular document)
So, the problem is that with every new pdf file, the first time I open it, Adobe Reader always opens the document NOT maximized.
I've tried changing a whole lot of settings inside Adobe Reader, but none of these settings helped.
PS: why does Adobe Reader needs to make a new version every week ? Can't they make the software in one time right ?
A work-around might be to make a Program Item on your desktop. Then right-mouse click it, select Properties, the Shortcut tab and set Run to "Maximized".
A second version would be to create a Program Item that does "start /max acrobat.exe" or "start /max acrord32.exe" as appropriate, possibly with path information.
Why do we have to find a "workaround"? Why can't Adobe just make software that works the way its supposed to?
Every time I open a new pdf file, Reader XI opens it NOT maximised. How do I stop this happening?? When I open a previously opened pdf it (sometimes) opens it maximised.
