Windows (Win 8 and Win 10) users may experience DNS leaks sometimes. The reason of it that Windows uses to resolve DNS all available adapters and IP addresses in parallel and takes the fastest responses. So if DNS of VPN is slower than DNS of your internet provider Windows will use DNS of the provider.
We made special configs for Windows 8+ which block all DNS except DNS of DeepWebVPN automatically.
