How to Change DNS Servers in Windows
Below are the steps required to change the DNS servers that Windows uses. However, the procedure is a little different depending on the version of Windows you're using, so be sure to take note of those differences as they're called out.
Open "Control Panel”, touch or click on Network and Internet.
Network and Sharing Center
Click or touch Network and Sharing Center to open that applet.
Now that the Network and Sharing Center window is open,
Click or touch the Change adapter settings link, located in the left margin.
From this new Network Connections screen, locate the network connection that you want to change the DNS servers for.
Tip: Wired connections are usually labeled as Ethernet or Local Area Connection, while wireless ones are usually labeled as Wi-Fi.
Open the network connection (Ethernet or Local Area Connection or Wi-Fi) you want to change the DNS servers for by double-clicking or double-tapping on its icon.
On the connection's Status window that's now open, tap or click on the Properties button.
On the connection's Properties window that appeared, scroll down in the This connection uses the following items: list and click or tap Internet Protocol Version 4 (TCP/IPv4) or Internet Protocol (TCP/IP) to select it.
Tap or click the Properties button.
Choose the Use the following DNS server addresses: radio button at the bottom of the Internet Protocol Properties window.
Note: If Windows already has custom DNS servers configured, this radio button may already be selected. If so, you'll just be replacing the existing DNS server IP addresses with new ones over the next few steps.
In the spaces provided, enter the IP address for a Preferred DNS server as well as an Alternate DNS server.
Note: You're welcome to enter just a Preferred DNS server, enter a Preferred DNS server from one provider with a Secondary DNS Server from another, or even enter more than two DNS servers using the appropriate fields found within the Advanced TCP/IP settings area available via the Advanced button.
Tap or click the OK button.
The DNS server change takes place immediately. You can now close any Properties, Status, Network Connections, or Control Panel windows that are open.
Verify that the new DNS servers Windows is using are working properly by visiting several of your favorite websites in whatever browser you're using. As long as the web pages show up, and do so at least as quickly as before, the new DNS servers you entered are working properly.
