you could also turn of the safe list in the firewall by moving the Firewall>Advanced>Firewall Behavior Settings > General Settings - to Custom.
If you want to stop programs that have already been allowed you will have to delete them from Firewall>Advanced>Network Security Policy > Application Rules
in Custom the firewall will not use the safe list however D+ will continue to unless you turn that off also.

This is a result of the Safe software list. It is designed to reduce the number of alerts that people have to deal with. The list contains programs that are common and from known sources. If you want to have control over those programs, you would have to write a rule controlling their permissions manually in the Firewall>Advanced>Network Security Policy page.
