 How to Block Ads on Windows 10 and 11 Using a Custom DNS

If you are tired of seeing annoying advertisements in your web browser and even inside some Windows apps, you do not need to install heavy ad-blocking extensions. You can block ads across your entire system simply by changing your PC's DNS server to a privacy-focused one, like AdGuard DNS.

Here is how to set it up safely:

1. Open Windows Settings: Press the Windows key + I on your keyboard.

2. Go to Network Settings:

   • Click on Network & internet on the left menu.

   • Click on Wi-Fi or Ethernet (depending on how your PC connects to the internet).

3. Edit DNS Server Assignment:

   • In Windows 11, click on Hardware properties.

   • Find the DNS server assignment option and click the Edit button next to it.

   • Change the setting from Automatic (DHCP) to Manual.

4. Enter the Custom DNS:

   • Turn on the IPv4 switch.

   • In the Preferred DNS box, type exactly: 94.140.14.14

   • In the Alternate DNS box, type exactly: 94.140.15.15

5. Save Changes: Click the Save button.

Your computer will now filter out incoming ad traffic automatically. If a specific website ever refuses to load because it detects an ad blocker, you can always revert the DNS setting back to "Automatic" to fix it.
