Windows border stripper is a program I designed to ease use of dual monitors while playing games. The idea is to run the games in "window" mode if available, but then to strip their borders so that they still appear to be running fullscreen. This provides the immersive gaming experience on one monitor, while allowing you to move your mouse off to the other monitor without minimizing your game. Specifically I wrote this program to use with Counter Strike Source by Valve, but it has come in useful a couple of other places as well.
