There's a ton of file comparison programs, but I'm looking for something specific and haven't found it yet. I need a graphical file comparison tool for Windows, suitable for non-power users - it should have an intuitive, simple and non-overwhelming interface, showing differencies in a way similar to this (Meld) or this (Kompare).
It should be Free Software and it should have a simple Windows installer (so that inexperienced users can install it effortlessly).
