I used this software for a long time, and it is targeted at people using a regular mouse but still want to have a trackpad ish experience (and making mac more mouse friendly). Things that I used day to day: smooth scrolling, horizontal scrolling, and middle click enhancements. It is free and open source.
This seems like a collection of shortcut remappings instead of a general window key to ctrl remap. That means that for example if Ctrl+p is not remapped, you can't use the win key.
I have an ahk script that's have a more general approach which maps window key to ctrl. It also remap the text navigation and mac style window switching.
