When the IPv6 protocol in Windows 10 network adapter is causing issues, listed here are the exact steps to fully turn off or disable IPv6 in Windows 10.

Windows 10 has built-in support for IPv6 protocol. If your ISP is providing IPv6 service, you can use it in Windows 10 without any other extra configuration or hassle. Though the IPv6 support is growing daily, it is still less abundant as IPv4. In fact, most internet services only use IPv4. Due to that, under certain situations, the built-in IPv6 in Windows 10 may cause compatibility issues with installed software or hardware that just works together with IPv4.

For example, some VPN connections, especially those provided in work environments are notorious when it comes to working alongside the IPv6. If the IPv6 causes problems or you just do not want it for whatever reason, it is simple to switch off IPv6 in Windows 10.

Within this simple and quick guide, allow me to show the particular steps to disable IPv6 in Windows 10.

How to disable IPv6 in Windows 10

You can switch off IPv6 from the network adapter settings in the Networking and Sharing Center in the user interface. Here're the steps.

Open the User interface in Windows 10.
After opening the control panel, set the "View by" around the top-right corner to "Large icons".
Click on the "Network and Sharing Center" option.
Here, click on the "Change adapter settings" link on the left panel.
Now, right-click around the active network adapter and choose "Properties".
Go to the "Networking" tab.
Here, uncheck the "Internet Protocol Version 6 (TCP/IPv6)" option.
Click on the "Ok" button to save changes.
Close the network connections as well as networking and sharing center windows.

That is all. You've successfully disabled the IPv6 protocol in Windows 10. The settings are automatically applied. There is no need for just about any system restart. If you think the settings aren't applied, disable and enable the network adapter. It'll force the settings to apply.

Note: If you have multiple network adapters then follow the same steps for each adapter.

PowerShell command to disable IPv6

The IPv6 in Windows may also be disabled using a PowerShell command. Here's the PowerShell command to show off IPv6.

Open the beginning menu.
Type "PowerShell", right-click around the result and select "Run as administrator".
After opening the PowerShell window as admin, execute this command to obtain all of the network adapter names with IPv6 enabled.
Get-NetAdapterBinding -ComponentID ms_tcpip6
Next, execute the below command to disable IPv6 on a specific network adapter. Replace "NetAdapterName" with the actual network adapter name you have using the earlier command.
Disable-NetAdapterBinding -Name "NetAdapterName" -ComponentID ms_tcpip6
(Optional) To turn off IPv6 on all network adapters, use the below PowerShell command.
Disable-NetAdapterBinding -Name "*" -ComponentID ms_tcpip6
Close the PowerShell window.

Once you execute the command PowerShell will disable the web Protocol version 6 in Windows 10.

How to turn off IPv6 via Command Prompt

You can use the great old Command Prompt to quickly disable the web protocol version 6. Here the steps you need to follow.
