How to disable IPv6 in Windows 8?

While working with calls from website via Internet, you may face problems with sound (clients can't hear you or you cannot hear him\her). The reason for this may be the fact that in Windows 8 IPv6 support (Internet Protocol Version 6) is enabled by default.

The IPv6 is the set of protocols that computers use to exchange information via Internet. In course of time IPv6 may replace completely IPv4 which is the most popular standard currently. The reason is that IPv6 allows to assign significantly larger number of IP addresses than it could be done with IPv4.

Well, until the new version of the Protocol has not replaced the older one, let us fix problems with sound transmitted via the Internet to Windows 8. Our task now is to disable IPv6 in Windows 8. Let's do that.

The 1st method

Deactivation of IPv6 in this way is the most correct because disabling this Protocol through the network interfaces may lead to some problems with applications that use the interface loopback and tunneling.

1. Click on the Windows button (start menu)

2. Enter the command regedit in the input field and press Enter

3. In the opened registry editor, follow this way: HKEY_LOCAL_MACHIN -> SYSTEM -> CurrentControlSet -> services -> TCPIP6 -> Parameters

4. In this folder click with the right button of mouse, select Create -> DWORD (32-bit) Value:


5. Name the newly created parameter Disabled Components and click Enter button

6. Click on the created parameter Disabled Components with the right mouse button and select “Modify”:


7. Set “FFFFFFFF” value to for DisabledComponents and click on “Ok”:


8. After reboot IPv6 will be disabled on all interfaces.

The 2nd method

1. Open the control panel. There are several ways to do this:

With use of mouse:

In normal mode (windowed) interface set the mouse pointer to the bottom right corner, and wait until the side menu with icons appears. Then click on “Settings” icon. In the window opened click on “Control Panel”.

In normal or brick mode interface move your mouse to the bottom left corner, and wait until the Start menu icon appears. Just click the icon with right button of the mouse and select Control Panel.

With use of keyboard:

Open the start menu (brick interface) and enter “Control Panel”. This automatically will start the search and operating system will show you Control Panel icon.

Press the key combination Win+R to open window of programs starting. Enter “Control Panel” in input fields, and then click on “Ok” or press Enter key.

2. Select “Network and Internet” in control panel:


3. Then click on “Network and Sharing Center”:


4. Pick up active Internet connection:


5. In the window that appeared, click on “Properties”:


6. Disable the checkbox next to the inscription “Internet Protocol version 6 (TCP/Ipv6)” and click on “Ok”:


7.  Click on “Information” in order to ensure that IPv6 is disabled:


If there is no IPv6in the window that has appeared, then IPv6 has been successfully disabled:


The 3rd method

1. Open the control panel. (If you do not know how to do it - see item 1 in the 1st method).

2. Click on the drop-down menu near “View” and select “Small icons”:


3. Select “Network and Sharing Center”


4. Click on the link “Change adapter settings”:


5. Click with right button of the mouse on the network connection that you need to change and select “Properties”:


6. Uncheck “Internet Protocol version 6 (TCP/Ipv6)” and click on “Ok” to save the changes:


We hope you will succeed, and this article has helped you.
