Hi Christoph, seems the USE_REGISTRY_LOOKUP is currently unused  (at least without additional defines that are not present usually) 

src/java.base/windows/native/libjli/java_md.c:52:#ifdef USE_REGISTRY_LOOKUP
src/java.base/windows/native/libjli/java_md.c:333:#ifdef USE_REGISTRY_LOOKUP


I am not sure if this even works any more.  Maybe Alan could comment on this ?
