if you try to change the settings of IPv4 or IPv6 of an VPN connection you're out of luck. The button is without function.
Open Network and Sharing Center -> Change Adapter Settings -> open Properties of a VPN Connection/Adapter -> switch to Networking Tab -> select IPv4 or IPv6 protocol -> click on the "Properties" button -> nothing happens
This button was working fine on Windows 7, 8 and 8.1
