Luckily, there is a free and open source tool for Windows and known as Simple DNSCrypt. This software allows you to configure DNS proxy on your Ethernet and WiFi connections in one click. There are various DNS servers from different countries available in it you can choose and apply.
You only have to configure it once and then you can use it anytime. It will change the DNS server for your PC according to the proxy DNS server you have chosen. And this way, you will be able to cover the leaks through your VPN. I have written a whole tutorial, how to configure DNS proxy in Windows to demonstrate how to use Simple DNSCrypt to create a DNS proxy.

So, if you more often use VPNs, then use these services to check if they are leaking anything like DNS or WebRTC leak, etc.
