In the deployment.properties file (from AppData\LocalLow\Sun\Java\Deployment\) there is a deployment.javaws.jre.0.registered property.
I could not find anything about the role of this option...
I just observed that when set to false, applets does not start. (so what is the difference with the enabled property ?
Is there somewhere a list of all deployment.javaws.jre properties with their documentation ?
