How to Disable IPv6 in Windows 7

How to Disable IPv6 in Windows 7?

1) Go to Start -> click on Control Panel -> click on View network status and tasks in Control Panel window -> click on change adapter settings in Network and Sharing Center window.

2) Network Connections window will appear. Here you right click on the network adapter (can be wireless adapter or wired Ethernet adapter) that you wish to disable IPv6 and click Properties.

3) In the network adapter properties window, untick Internet Protocol Version 6 (TCP/IPv6) and click OK.

Note: This method disables IPv6 on your LAN interfaces and connections, but does not disable IPv6 on tunnel interfaces or the IPv6 loop back interface. You need to make change in Windows registry in order to disable the IPv6 on tunnel interfaces.

4) Type regedit in command prompt to launch registry editor, proceed to locate following registry item in Registry editor.


5) If the Disabled Components item is unavailable, you must create it in following format by going to Edit -> New -> DWORD (32-bit) Value and set the value to 0xffffffff (just type ffffffff). This will disable all IPv6 features except the IPv6 loop back interface, finally click OK. Repeat the same process on other network adapters and finally restart computer.
