How can you make seperate windows open up maximized all of the time.  Have tried clicking the Max button and going to file and exit, but they still open up small.

I have had that problem too. I would maximize a window, then close the program; but the next time I open it it's in a small window again. If the window for a particular program refuses to retain its maximized setting, I  drag the edges of the window all the way out so that it fills the screen, just like "maximized", but not actually maximized.  It usually remembers to return at that size the next time I open the program. And for whatever reason, it seems to remember better if I close the program with File-Close or File-Exit than by clicking the "X" in the corner.  Doesn't work with everything, though.

   That all depends on the programmer and how he programmed the program.  If he wrote in code to remember that it was maximized and then open that way the next time, it will do that.  If not, it won't.
   Sometimes they are written so that they remember the last size the screen was but not whether it was maximized or not.  Again this all depends on how the program was written.

The following suggestion was sent to me by Dean Frisch.  It only applies if the program you want to run is started by a shortcut (like, the items on the desktop and start menu).

Another potential way to maximize any program on startup would be to access the Properties dialog box and change the selection in the "Run" category from Normal to Maximized. Access the properties for desktop shortcuts by right-clicking on the desktop icon, selecting properties and then select the Shortcut Tab. Access the same properties dialog for actual programs by right-clicking the appropriate item from the start menu.

Using either of these methods would then retain the flexibility to also have the third option remain available when you wanted the window to be "reduced" but not minimized.
