So now when you know ‘What is Google DNS’ in simple words, you may want to use Google DNS on your Windows computer instead of default ISPs DNS. Just like OpenDNS, Google DNS can be easily setup on Windows based computer (XP, Vista and 7). It promises faster internet browsing as a result of quicker resolving of DNS for websites you surf.

2. Click Network and Internet > Network and Sharing Center > Manage network connections.
3. Right click Local Area Connection or Wireless Network Connection and then click Properties.
4. Select the Networking tab, click Internet Protocol Version 4 (TCP/IPv4) and then click Properties.
