Hello,
some time ago I did a small project which is able to force minimize games
(or plain applications, but that's not the point) which refuse to go down using
standard methods like Alt+Tab or WinKey.

You can find it and its source here: http://home.arcor.de/m3ep/software/Minimizer.7z

However:
This tool doesn't touch video settings (resolution, gamma, brightness, contrast)
because I don't know how to do it. I searched the MSDN-Library up and down but
everything I found was for Windows CE exclusively.

So you only get optimal results if you run your game with desktop settings.
This is a small drawback which I want to fix.
