How to change your DNS server on Windows

In this article, we’ll explain how to change your DNS settings on any Windows computer. DNS stands for Domain Name System. Think of DNS as a phone book for the internet that translates domain names (like “”) into numeric IP addresses (like “”), allowing you to visit websites without having to remember their IP. By changing DNS, you can direct your internet connection to use a more reliable DNS server. This can help if you’re having trouble connecting to certain websites or applications, encountering Bitdefender update errors, VPN errors, or if your internet speed is slow.

We’ve got a short video that shows you how to easily change the DNS server, or you can read the steps below.
