Simple example for possible issues (might be more):
Cygwin seems to modify the global REGISTRY with a "Install for
everyone" (as Admin). What will happen then? Can Cygwin installations
installed as non-admin interact via Windows REGISTRY, or other
unexpected ways? So testing by a non-expert like me might not uncover
such things immediately, so I better ask the experts here

@Corinna Vinschen ?
