The Windows 10 VPN connecting GUI is horrible. You cannot connect to VPN from the tray icon popup. Instead, after you find your VPN on the list and click it, you are redirected to the VPN manager. Win 8.1 was much better allowing you to connect to a VPN directly from the flyout. An additional UI problem with Windows 10 is scrolling the WiFi/VPN list is much harder. Frequently I end up clicking on an item while trying to grab the scroll bar. With windows 8.1 this bar is much easier to navigate, especially when your list has many networks populated.
