WinAPI hook that replaces registry entries

Trying to bring any program to a portable-version, I often encounter a registry problem. Many people like to keep their settings there, which makes them unbearable, non-portable (examples are Last.fm, ProcExp, etc)



There was an idea - to write a launcher, which will broadcast calls to a specific branch in the registry to read / write from a file (for example, .ini)



Maybe such a program already exists? Googling led nowhere. You can try it yourself, but WinAPI is obviously not enough knowledge. Maybe someone has any developments in this direction?
